In 2025, the New Zealand Government introduced significant changes to the building and construction sector, the most significant since the Building Act 2004. These updates are designed to make builders more accountable, protect homeowners, and simplify the building process. Key reforms include the shift from 'joint and several liability' to proportionate liability, the introduction of mandatory home warranties for new builds, and streamlined building consent processes. If you’re planning a new build, it’s essential to understand what’s changed and why it matters for your project.
