CCA Adjudication vs Litigation — Which Dispute Pathway in NZ Construction?

What is CCA Adjudication and What Disputes Does It Cover?

CCA adjudication is a mandatory statutory process under Part 3 of the Construction Contracts Act 2002. Any party to a construction contract can refer a payment dispute to adjudication. The other party cannot refuse. The right to adjudicate cannot be contracted out of — a special condition that says "no adjudication" or "adjudication only after mediation is exhausted" is void against the statute.

The adjudicator's jurisdiction is limited to payment disputes under Section 25 of the CCA. This covers:

• Whether a payment claim is payable and in what amount
• The date on which payment is due
• Disputes about variation entitlements and their value
• Disputes about retention money calculations
• Claims for additional time and costs where these are linked to a payment claim

The adjudicator cannot determine wider contractual rights, general damages, defect liability beyond the payment context, or matters that were never referred in the adjudication notice. Jurisdictional overreach by an adjudicator is a ground for setting aside the determination — one of the few grounds that will succeed. The English Court of Appeal in Carillion Construction Ltd v Devonport Royal Dockyard Ltd [2005] EWCA Civ 1358 confirmed that jurisdictional challenges succeed only where the adjudicator clearly stepped outside the scope of what was referred, and that courts protect the adjudication regime from technical arguments designed to defeat it.

Adjudication is described in the case law and commentary as a "rough and ready" process. It is not a full merits inquiry. Adjudicators work to tight timeframes, on documentary submissions, without live witness evidence in most cases. The trade-off is speed and cash flow — the right answer is reached faster, even if not every nuance is explored.

What is Litigation and When Do Construction Disputes Go to Court?

Litigation means commencing formal proceedings in the District Court or High Court of New Zealand. Most construction disputes of significant value end up in the High Court if they go to court at all. The District Court has jurisdiction up to $350,000. Claims above that threshold belong in the High Court.

Construction disputes go to court when:

• The dispute is not a "payment dispute" within the CCA definition — defects claims, professional negligence, breach of contract on non-payment matters, tortious claims
• A party wants to finally determine a dispute after losing an adjudication — the adjudication determination is interim only; litigation provides the final answer
• Summary judgment is sought to enforce an undisputed CCA debt where the respondent failed to provide a payment schedule (no defence available on the merits in that scenario)
• The parties need discovery, witness evidence, or expert evidence at a depth that adjudication's compressed timeframes cannot accommodate
• The claim involves multiple parties across a contractual chain and a single proceeding is more efficient than multiple adjudications

Arbitration is a third pathway — private, binding, and with a full hearing process. It is common in large infrastructure and PPP contracts where the head contract specifies arbitration. Arbitration is not this article's focus, but it sits between adjudication and litigation: more procedurally rigorous than adjudication, private unlike litigation, and produces a final and binding award.

What Are the Time Differences?

Time is the most important practical distinction between the two pathways.

CCA adjudication runs on a statutory clock. Once a notice of adjudication is served, the adjudicator must be agreed or appointed within 3 working days. The claimant provides its submission within 5 working days of the adjudicator's acceptance. The respondent has 5 working days to respond. The adjudicator then has 20 working days from receiving the respondent's response to issue the determination (extendable to 30 working days by agreement where complexity warrants). In practice, from notice to determination is 6 to 8 weeks in a typical payment dispute. That is the entire contested process, from trigger to enforceable outcome.

Court litigation works on a fundamentally different timescale. Filing proceedings, service, pleadings, interlocutory applications, discovery, evidence exchange, and a hearing date can take 12 to 36 months for a contested construction claim. Complex High Court cases with significant quantum disputes, expert witnesses, and multiple parties take longer still. The courts are not resourced to match the urgency of a construction payment dispute, nor are they designed to be.

What Are the Cost Differences in Time-and-Effort Terms?

Construction proceedings are expensive in both pathways, but the effort profile is very different.

In adjudication, most of the work is front-loaded. The claimant must prepare a complete submission within 5 working days of the adjudicator's acceptance. There is no room for staged evidence disclosure or later supplementation as a matter of right. The quality of the initial submission directly determines the outcome. Legal and advisory costs are incurred in a concentrated burst over 6 to 8 weeks. For current adjudicator fee schedules, contact the Building Disputes Tribunal (BDT), NZDRC, or the Resolution Institute directly — fee levels depend on complexity and the adjudicator appointed. Request a fee estimate before committing to a particular adjudicator.

Litigation costs are spread over a much longer period but typically aggregate to a substantially higher total for a fully contested matter. Pleadings, discovery, interlocutory applications, expert evidence, and a full hearing generate significant legal fees. Cost awards in litigation follow the "costs follow the event" principle more consistently than adjudication, but even a successful plaintiff recovers only party-party costs, not solicitor-client costs in full. Contact your legal team for a fee estimate appropriate to the specific dispute — generalised figures are not reliable for this purpose.

The cost-benefit calculation for adjudication is straightforward: if you have a strong payment claim and clear documentation, the cost of adjudication is almost always worth it compared to waiting for litigation. If your claim is weak, the same analysis goes the other way — a lost adjudication has real costs and delays your ability to litigate the underlying dispute.

When Should You Use Adjudication?

Adjudication is the right pathway when:

• You have a clear payment dispute. A payment claim was served, a payment schedule was not provided on time, or the scheduled amount was not paid. These are the strongest adjudication cases. The statutory consequences under Section 22 mean the respondent's position is already compromised before the adjudicator considers the merits.
• Cash flow is the immediate problem. If the dispute is holding up payment that your business needs to operate, adjudication puts money in your account in weeks, not years.
• Your documentation is strong. Adjudication is a document-based process with minimal time for elaboration. Well-organised contemporaneous records, properly structured payment claims, and a clear calculation of the amount in dispute win adjudications. Undocumented claims fail.
• The amount is material but not enormous. Adjudication is proportionate to disputes where the cost of the process is justified by the amount in issue. It works well across a wide range of claim values — from subcontract disputes in the low six figures to major variation claims on large infrastructure contracts.
• Speed matters more than comprehensiveness. If you need an answer and you need it fast, adjudication delivers. If the dispute requires extensive expert evidence, site inspections, and witness testimony over multiple days, litigation or arbitration will serve you better in the long run — but adjudication gets you cash while that process runs.

When Should You Litigate Instead?

Litigation is the right pathway when:

• The dispute is not a payment dispute. Defects claims, professional negligence, latent conditions liability, disputes about project completion standards, and general damages sit outside adjudication's jurisdiction. These go to court from the start.
• You need a final determination. Adjudication is interim only. If you want a result that cannot be re-litigated (subject only to appeal), you need a court judgment or arbitration award. Some parties use adjudication to get cash flowing and then litigate to finally resolve the underlying dispute.
• You lost an adjudication and believe the adjudicator was wrong. Your remedy is to litigate (or arbitrate) the underlying dispute. The adjudication determination remains binding and must be complied with while proceedings continue. You cannot resist enforcement because you think the adjudicator reached the wrong answer.
• The dispute involves multiple parties across a contractual chain. A single set of court proceedings can bring in the principal, contractor, subcontractor, designer, and their respective insurers. Multiple parallel adjudications addressing the same factual dispute from different contractual angles is inefficient and risks inconsistent outcomes.
• The claim requires expert evidence at depth. Adjudication cannot accommodate a month-long hearing with five expert witnesses on geotechnical conditions or design liability. These cases belong in the High Court or in arbitration where the procedural framework matches the complexity.

Can You Do Both? What About the Temporarily-Final Principle?

Yes. Section 25 of the CCA confirms that the right to adjudicate exists even while other proceedings are on foot. A party can adjudicate a payment dispute while separate court proceedings address the wider contractual position. This is common on large infrastructure projects where a contested variation claim has both a payment aspect (adjudicatable) and a programme entitlement aspect (to be litigated).

The key concept here is the "temporarily-final" principle. An adjudication determination is:

• Immediately binding — both parties must comply with it now
• Immediately enforceable — the successful party can register it as a District Court judgment and use standard enforcement processes
• Not permanently final — either party can commence litigation or arbitration to determine the underlying dispute, and the final court judgment or arbitration award will correct any over or under-payment from the adjudication

The Court of Appeal confirmed this position clearly in Bayley v Knowles [2010] NZCA 479. The court's role in enforcement proceedings is supervisory only. It will enforce the determination unless there is a jurisdictional defect or a breach of natural justice. Disagreement with the adjudicator's reasoning, or a belief that the adjudicator reached the wrong answer on the facts, is not a basis for resisting enforcement. The same principle is well-established in English authority: in Macob Civil Engineering Ltd v Morrison Construction Ltd [1999] BLR 93, the Technology and Construction Court confirmed that adjudicator decisions are enforced "regardless of whether the adjudicator is right or wrong." The right remedy for a wrongly decided adjudication is arbitration or litigation on the underlying dispute — not resistance to enforcement.

In practice, this means: if you receive an adjudication determination against you, pay it. Then commence proceedings to finally resolve the underlying dispute if you believe the adjudicator was wrong. This is not unfair — it is the deliberate design of the regime. Cash flow continues. Projects are not held hostage to dispute. The final result is determined separately.

Strategic Considerations

The choice between adjudication and litigation is not always binary. Most experienced construction lawyers and commercial managers use both pathways strategically across the life of a dispute.

Use adjudication to apply cash flow pressure. A claimant with a strong payment claim can adjudicate quickly. The determination, if successful, creates an immediate cash flow event for the respondent. This often prompts negotiation and settlement of the wider dispute on terms more favourable than the claimant would have achieved by waiting for litigation.

Document the claim before you adjudicate. Adjudication is won or lost in the initial submission. There is no discovery process, no opportunity to request documents from the other side, and limited ability to supplement your case after the respondent has responded. The time to organise the claim file is before you serve the notice of adjudication — not after. Provan's Contracts domain is built around this: every payment claim, every variation, every notice, every piece of correspondence is logged and retrievable from day one, so when a dispute crystallises the claim file is ready.

Be realistic about what adjudication can decide. An adjudicator working to a 20-working-day determination deadline is making a considered interim decision, not a comprehensive final ruling. If the dispute involves contested expert evidence on structural defects, delay analysis across a two-year programme, or allegations of professional negligence requiring detailed technical inquiry, adjudication is the wrong venue. Use it for what it does well — payment disputes with clear documentation — and reserve litigation for the disputes that genuinely need it.

Losing an adjudication does not mean losing the dispute. Interim binding means the determination stands until overturned. A party who pays out on an adjudication and then litigates to final judgment can recover the over-payment in the court proceedings. This is the designed safety valve. Losing an adjudication is not the end of the road, but it does mean writing a cheque while the road continues.

Consider relationships. Adjudication is adversarial. Commencing adjudication signals that the relationship has broken down, or at least that the commercial stakes outweigh the relationship cost. On a project where ongoing collaboration matters, consider whether negotiation or mediation should be attempted first. If the other party is simply refusing to pay a valid claim with no genuine dispute, adjudication may be the most commercially rational response regardless of relationship dynamics.

Confidentiality is a real advantage for adjudication in certain disputes. If the dispute involves commercially sensitive information — contract pricing, internal cost data, project performance records — adjudication keeps that information out of the public record. Court proceedings do not. Parties sometimes adjudicate specifically to preserve confidentiality, with the underlying rights to be determined privately through arbitration if necessary.

Frequently Asked Questions

What types of disputes can go to CCA adjudication vs litigation?

CCA adjudication is limited to payment disputes under a construction contract: disputes about amounts claimed, payment claim validity, variation entitlements, retention calculations, and the date payment is due. Litigation handles disputes that fall outside the payment scope — general damages, defects claims, professional negligence, breach of contract where no payment claim is in dispute, and final determination of any matter after adjudication. If your dispute is not about a payment claim, you are in litigation territory from the start.

How long does CCA adjudication take compared to court proceedings?

CCA adjudication runs from notice to determination in approximately 6 to 8 weeks in a typical case. The adjudicator must determine within 20 working days of receiving the respondent's response, extendable to 30 working days by agreement. Court litigation for a contested construction dispute typically takes 12 to 36 months from filing to judgment, depending on court load, complexity, and whether interlocutory steps are required. Summary judgment on an undisputed CCA debt can be faster, but contested litigation is measured in years, not weeks.

Can an adjudication determination be appealed?

Not in the traditional sense. A CCA adjudication determination is interim binding and is enforceable as a District Court judgment. The court will not review the merits of the determination at the enforcement stage, as confirmed by Bayley v Knowles [2010] NZCA 479. If you believe the adjudicator reached the wrong answer, your remedy is to pursue the underlying dispute through arbitration or court litigation after complying with the determination. The grounds for resisting enforcement are narrow: jurisdictional error or breach of natural justice — not disagreement with the outcome.

Can you run adjudication and litigation at the same time?

Yes. Section 25 of the CCA confirms the right to adjudicate exists even if other proceedings are on foot. A party can adjudicate a payment dispute while separate court proceedings address wider contractual issues. The adjudication determination is interim binding and must be complied with regardless of the parallel proceedings. The litigation or arbitration then finally determines the underlying rights, and any over or under-payment from the adjudication is corrected in the final judgment or award.

Is construction litigation confidential in New Zealand?

No. Court proceedings in New Zealand are generally public. Judgments are published, proceedings are heard in open court, and the public record is accessible. CCA adjudication is a private process. Submissions, evidence, and the determination are not published unless the parties agree or a court enforcement proceeding puts the determination on the public record. Confidentiality is a meaningful practical advantage of adjudication for parties who want to resolve disputes without public exposure.
