New Zealand’s Biggest Building Consent Reform: What You Need to Know

  • Faster approvals: Reduced red tape and less council risk-aversion.
  • Consistent decisions: Councils can share and standardise consenting.
  • Fairer liability: Each party responsible only for their share of work.
  • Lower costs: Less duplication, fewer delays, and cheaper compliance.

The New Zealand government has announced what many are calling the most significant overhaul of the building consent system since the Building Act 2004. These reforms promise to speed up consents, reduce duplication, and draw clearer lines of responsibility.

At Villaworx Construction, we’re excited about the potential for these changes to make the consenting process smoother, more efficient, and more predictable for homeowners and builders alike.

In this post, we break down the key reforms, explore why they’re positive, and how they might affect your next project.

What’s Changing & Why It Matters

 

1. From “Joint and Several Liability” → “Proportionate Liability”

Under the current system, councils (and sometimes ratepayers) can be held liable for defects in building work, even when the fault lies with other parties who are no longer around or bankrupt. This leads to a risk-averse approach by councils, slowing approvals, demanding extra checks, and creating costly delays. The reform introduces proportionate liability: each party is only responsible for the share of work they executed. This shift reduces the burden on councils and should help them feel less exposed, allowing them to approve more confidently and efficiently.

2. Encouraging Council Consent Consolidation

Currently, New Zealand has 66 different Building Consent Authorities (BCAs), each interpreting the Building Code slightly differently. That discrepancy means a design might be accepted in one region but rejected in another. The reforms allow councils to voluntarily consolidate or share consenting functions, standardise systems, share inspectors/IT, and reduce duplication.

This means:

  • More consistent decisions across regions
  • Less need to rework plans just because you’re crossing council lines
  • Potential cost savings passed on to building clients

3. Exemptions, Modern Tools & Efficiency Boosts

Beyond liability and structure, the reforms also look at:

  • Which building work can be exempt from consent (where safe and reasonable)
  • Use of remote inspections, technology, and process streamlining to speed up approvals.
  • Easing restrictions on imported building products (if they meet standards) to widen material options.

All of these changes align with the government’s aim to make it easier to build, especially for homes and infrastructure.

The Positive Upside for Homeowners & Builders

Here’s what to watch for:

  • Faster approvals: With less risk aversion and more unified systems, consents should move quicker.
  • More certainty: Reduced variability across councils means fewer surprises or plan rejections just because of location.
  • Fairer risk allocation: Builders, architects, and developers will carry more responsibility (but also more clarity).
  • Lower costs: Fewer delays, duplication, and rework can reduce holding costs, consultant fees, and compliance burdens.
  • Innovation freedom: With less fear of liability, councils may be more open to non-standard designs or new materials that meet safety codes.
  • Insurance & warranty options: The government is exploring mechanisms like professional indemnity insurance and home warranties to safeguard homeowners and support new liability rules.

What Builders and Homeowners Should Do Now

  • Stay informed. The reforms are still being shaped; a Bill is expected in early 2026.
  • Talk with your local BCA. As councils explore voluntary consolidation, knowing your BCA’s plans is helpful.
  • Plan for warranties & insurance. If these become mandatory or standard, choosing parties who are insured/warrantied will matter.
  • Use modern systems and tech. Embrace remote inspections, better documentation, and compliance tools to stay ahead.
  • Talk to builders early. Under a more efficient consenting system, early collaboration between owners, designers, and builders will pay off more.

Final Thoughts

New Zealand’s building consent system reform represents a bold step forward, balancing fairness, clarity, and efficiency. While the details are still emerging, the direction is clear: less risk paralysis, fewer council bottlenecks, and a smarter, more capable consenting ecosystem.

At Villaworx Construction, we’re excited about how these changes can make future projects smoother, faster, and more predictable, for us and most importantly our clients. If you’re planning a build or renovation, we’d love to talk through how this reform might benefit your project.
