Construction Contracts Act Adjudication NZ

What is adjudication, and suspension rights in construction">Construction Contracts Act Adjudication?

Construction Contracts Act adjudication is New Zealand's statutory dispute resolution process for construction payment disputes. Established under Part 2 of the Construction Contracts Act 2002 (CCA), it provides a rapid interim resolution mechanism that keeps projects moving while payment disputes are resolved.

Unlike traditional litigation or arbitration, CCA adjudication is designed to be fast, with strict timeframes measured in weeks rather than months. The adjudicator's determination is immediately enforceable, though parties retain the right to challenge the decision through later proceedings.

The process applies to all construction contracts in New Zealand, regardless of their value or complexity. Whether you're dealing with a $50,000 subcontract dispute or a $50 million main contract claim, the same adjudication framework applies.

When Can You Apply for Adjudication Under the CCA?

You can apply for Construction Contracts Act adjudication when there's a "dispute about payment" under a construction contract. Section 24 of the CCA defines this broadly, covering disputes about:

• The amount of a progress payment
• Whether a payment claim is payable
• The date on which payment is due
• The calculation of retention money
• Variations and their payment
• Claims for additional time and costs

The dispute must relate to a "construction contract" as defined in Section 7 of the CCA. This includes contracts for construction work, associated professional services like design and project management, and contracts for hiring plant or supplying materials where the supplier also provides associated services.

The CCA Adjudication Process Step by Step

Construction Contracts Act adjudication follows a structured process with tight timeframes:

1. Application for Adjudication

The claimant submits an application to an adjudication nominating body (like ACENZ, IPENZ, or RICS). The application must include the payment claim, any payment response, and supporting documentation. The nominating body then appoints an adjudicator.

2. Adjudicator Appointment

The adjudicator must be appointed within 5 working days of the application being made. Once appointed, the adjudicator has jurisdiction to determine the dispute.

3. Response Period

The respondent has 5 working days from receiving the application to provide a response to the adjudicator. This response can include counterclaims or set-off arguments.

4. Reply Period

The claimant then has 2 working days to reply to the response, though the adjudicator may extend this if necessary.

5. Determination

The adjudicator must make their determination within 20 working days of their appointment (or 25 working days for complex disputes). The determination must be in writing and include reasons.

Stage	Timeframe	Key Actions
Application	Within 20 working days of payment response	Submit application with supporting documents
Appointment	5 working days	Nominating body appoints adjudicator
Response	5 working days	Respondent submits response and counterclaims
Reply	2 working days	Claimant replies to response
Determination	20 working days (25 for complex disputes)	Adjudicator issues written determination

What Powers Do CCA Adjudicators Have?

Under the Construction Contracts Act adjudication process, adjudicators have extensive powers to resolve payment disputes effectively:

• Determine payment amounts: The adjudicator can decide how much (if anything) is payable under a payment claim
• Award interest: Interest can be awarded on overdue amounts from the due date until payment
• Allocate costs: The adjudicator decides who pays the adjudication fees and can award costs to the successful party
• Set-off decisions: They can determine whether claimed set-offs or counterclaims are valid
• Procedural directions: Adjudicators can manage the process, request additional information, and extend timeframes if necessary

Costs of Construction Contracts Act Adjudication

Understanding the costs involved in Construction Contracts Act adjudication helps you budget for disputes and assess whether adjudication is worthwhile:

Adjudicator's Fees

Adjudicator fees vary significantly with experience and dispute complexity. Hourly rates and total cost ranges are not standardised; both depend on the adjudicator and the matter. For current rates, contact the relevant nominating body (AMINZ, NZIA, ACE NZ) for fee schedules or request a fee estimate from the proposed adjudicator before appointment. Build a fee allowance into the dispute budget proportionate to dispute complexity and value.

Nominating Body Fees

Nominating bodies (AMINZ, NZIA, ACE NZ, RICS) charge application fees that are listed on their respective websites. These are typically modest relative to adjudicator and legal costs. Confirm current fees with the chosen nominating body before applying.

Legal Costs

While parties can represent themselves, most engage lawyers for anything beyond simple payment claims. Legal cost depends on the firm, the seniority of the team engaged, the complexity of the dispute, and the volume of documentary record involved. A straightforward payment dispute typically costs less than a contentious entitlement dispute with significant time-and-cost claim implications. Request a fee estimate from your legal team upfront and revisit as the matter progresses.

Cost Allocation

The adjudicator decides who pays these costs. Generally, the unsuccessful party pays the adjudicator's fees and may also pay the successful party's costs, though this isn't automatic.

Enforcement of CCA Adjudication Determinations

One of the key strengths of Construction Contracts Act adjudication is that determinations are immediately enforceable, even if the paying party disagrees with the decision.

Section 59 of the CCA makes adjudication determinations enforceable as judgments of the District Court. This means you can use standard debt recovery procedures including:

• Attachment orders against bank accounts
• Charging orders against property
• Warrant to seize property
• Bankruptcy or liquidation proceedings

The courts have consistently supported the "pay now, argue later" principle underlying CCA adjudication. Challenges to adjudication determinations are limited to narrow grounds like jurisdictional errors or breach of natural justice, not disagreement with the merits of the decision. The Court of Appeal in Bayley v Knowles [2010] NZCA 479 confirmed that the courts apply a deliberately limited review at the enforcement stage and will not allow enforcement to become re-litigation of the underlying dispute. The English authority Macob Civil Engineering Ltd v Morrison Construction Ltd [1999] BLR 93, widely cited in NZ adjudication practice, applies the same enforcement-first principle.

Common Mistakes in CCA Adjudication Applications

Having seen numerous Construction Contracts Act adjudication applications over the years, certain mistakes occur repeatedly:

Timing Errors

The most common error is missing the 20 working day deadline for applying. This deadline is strict with no discretion to extend it, and missing it means losing your right to adjudicate that particular claim.

Incomplete Documentation

Applications often fail to include all relevant contract documents, correspondence, or supporting evidence. The tight timeframes mean there's limited opportunity to supplement missing documentation later.

Jurisdictional Issues

Some applications fall outside the CCA's scope. For example, disputes about pure consultancy services without a construction component, or disputes that aren't really about payment.

Poor Claim Presentation

Given the short timeframes, adjudicators rely heavily on clear, well-organised submissions. Poorly presented claims with unclear calculations or missing logic often fail even when the underlying entitlement is valid.

Alternatives to CCA Adjudication

While Construction Contracts Act adjudication is often the fastest route to resolve payment disputes, it's not always the best option:

Direct Negotiation

Many disputes can be resolved through direct negotiation between project teams, especially when there's an ongoing relationship to preserve. This avoids the cost and adversarial nature of adjudication.

Mediation

Mediation can be effective for disputes involving multiple issues or where preserving relationships is important. It's typically faster and cheaper than adjudication, though outcomes aren't binding unless formalised in a settlement agreement.

Expert Determination

For technical disputes about quantities, quality, or compliance, expert determination by a relevant specialist can be more appropriate than adjudication by a legally-trained adjudicator.

Litigation or Arbitration

These remain available for disputes outside the CCA's scope, or where the amounts involved justify more comprehensive proceedings. However, they typically take many months or years to resolve.
