131: Part 4A breaches

Undertaking residential building work in New Zealand carries important legal responsibilities, particularly where the contract value is $30,000 or more (including GST). This threshold, referred to in the Building Act 2004 as the prescribed minimum price, triggers mandatory requirements under:

• Part 4A of the Building Act 2004
• the Building (Residential Consumer Rights and Remedies) Regulations 2014.

These requirements are designed to protect both homeowners and contractors by ensuring transparency, accountability, and fair dealing throughout the building process.

Compliance with Part 4A of the Building Act 2004 and associated regulations is a fundamental responsibility for anyone undertaking residential building work in New Zealand. By providing the required documentation and adhering to ethical standards, contractors not only meet their legal obligations but also contribute to a more transparent, fair, and professional construction industry.

Key documents required

When carrying out residential building work, at or above the prescribed minimum price, contractors must provide:

1. Disclosure information
2. Prescribed checklist
3. Residential building contract
4. Completion documentation

Even for projects under $30,000, these documents must still be provided if requested by the client—and it is considered best practice to provide them regardless of project size.

1. Disclosure information

The disclosure statement gives homeowners critical information about the contractor before entering into a contract. Its purpose is to enable clients to make informed decisions. Required information includes:

• contractor’s business details
• key contact person responsible for the work
• insurance coverage, such as:
  • contract works insurance
  • public liability
  • professional indemnity
  • plant and vehicle insurance
• details of any guarantees or warranties.

Important note: the disclosure form must follow the exact format prescribed in Schedule 1 of the Regulations. Contractors cannot alter or customise the document.

2. Prescribed checklist

The prescribed checklist (Schedule 2 of the Regulations) is a standardised document intended to educate homeowners about their rights and responsibilities.

It covers:

• the nature of the building work
• project management and structure
• selecting competent contractors
• pricing and payment structures
• contract terms
• communication expectations
• dispute resolution processes.

Key requirements are:

• it must be provided with the disclosure statement
• it must not be modified, branded, or altered in any way.

The checklist ensures that homeowners enter into contracts with a clear understanding of what to expect.

3. Residential building contract

A written contract is mandatory for projects valued at $30,000 or more.

Minimum written contract requirements are:

• names and contact details of all parties
• contract date
• description of the work and site address
• expected start and completion dates
• contract price or pricing method (for example, fixed price or hourly rate)
• payment schedule and invoicing details
• procedures for variations
• how delays will be managed
• processes for addressing defects
• dispute resolution mechanisms
• confirmation that disclosure and checklist documents were provided.

Failing to include these elements can leave both parties exposed to legal and financial risks.

4. Completion documentation

Upon completion of the building work, contractors must provide:

• maintenance information
• details of warranties and guarantees
• information on any ongoing insurance.

This ensures the homeowner can properly maintain the building and understand their long-term rights.

Legal framework and consumer protection

Part 4A of the Building Act operates alongside several important laws, including the:

• Fair Trading Act 1986
• Consumer Guarantees Act 1993.

It also incorporates:

• implied warranties that automatically apply to residential building work
• remedies available if those warranties are breached
• processes for addressing building defects.

These provisions collectively strengthen consumer protection in the residential construction sector.

Code of Ethics for Licensed Building Practitioners (LBPs)

The Code of Ethics, introduced in 2021 and fully enforced from 25 October 2022, reinforces compliance obligations.

Clause 10: Compliance with the Law

Licensed Building Practitioners must comply with:

• the Building Act 2004
• relevant regulations, including the Consumer Rights and Remedies Regulations.

Failure to comply can result in disciplinary action.

Real-world consequences

A recent Board decision resulted in:

• a $1,500 fine
• additional $1,500 in costs.

This penalty was imposed because the contractor:

• failed to provide disclosure information
• did not supply the checklist
• did not have a compliant contract.

Why these requirements matter

These legal obligations are not just administrative tasks—they are essential safeguards that:

• promote transparency and trust
• reduce disputes
• clarify expectations
• protect both contractors and clients.

Contractors who consistently follow these requirements demonstrate professionalism and reduce their exposure to legal risks.

Best practice recommendation

Even when not legally required (i.e., projects under $30,000), contractors should:

• provide disclosure information
• include the prescribed checklist
• use written contracts.

Taking these steps enhances credibility while helping to build stronger client relationships.
