Building Amendment Bill introduced to support faster, fairer building system

The Government has introduced the Building Amendment Bill, which proposes a range of changes to New Zealand's building system, including reforms to liability settings, consenting processes and building research funding.

The Bill had its first reading in Parliament

on 2 July and has now progressed to a select committee process, giving industry stakeholders and the public an opportunity to provide feedback on the proposed changes.

The reforms are designed to make it easier, faster and more cost-effective to build, while supporting a more efficient and productive construction sector, with strengthened protections for homeowners.

Key proposed changes include:

  • moving from joint and several liability to proportionate liability in the building system
    • introducing mandatory home warranties for new builds and major renovations valued over $100,000
    • requiring professional indemnity insurance for building design professionals
  •  making it easier for councils to work together or combine Building Consent Authority functions
  • introducing a fast-track 10-day consenting pathway for eligible residential buildings with solar generation and sustainable features and reducing Project Information Memoranda (PIM) processing times from 20 to 10 working days
  • expanding options for the construction of granny flats, including allowing eligible offsite-built units to be constructed before a PIM is issued
  • modernising building research funding by combining the Building Research Levy with the Building Levy and introducing a more contestable model.

Together, the changes are intended to support a more productive building and construction sector that can deliver the homes, buildings and infrastructure New Zealand needs.

Submissions are open until 15 November 2026.
