New Zealand faces a significant housing crisis, with over 20,000 households on social housing waiting lists and average home values reaching six times the national income.Beyond affordability issues, the country struggles with systemic building defects costing an estimated $2.5 billion annually.Over 20,000 inspections fail yearly, creating avoidable costs that drive up housing prices.

The government's push for self-certification for trusted builders aims to streamline approvals and reduce delays, but experts warn this approach risks normalizing poor quality.Current reforms could shift responsibility from councils to builders, potentially worsening defects if not paired with structural improvements.

A field trial in Auckland showed reducing inspection failures by 15% through proactive quality checks, highlighting the need for preventive measures over reactive fixes.

Without systemic changes, self-certification may cut costs but fail to address root causes, leaving homeowners bearing higher expenses and exacerbating housing shortages.
