Let's be direct: renovation costs in New Zealand are high. Labour costs, material supply chain issues, and council compliance requirements mean that budgets balloon quickly. Here's what to actually expect.
Average Costs by Room
Based on our 2026 survey of Auckland, Wellington and Christchurch contractors:
- Kitchen renovation: $25,000–$70,000+
- Bathroom renovation: $15,000–$45,000
- Laundry: $8,000–$20,000
- Open-plan living: $30,000–$80,000+
The Hidden Costs Nobody Tells You About
Council building consents typically cost $1,500–$4,000 and add 4–8 weeks to your timeline. Asbestos removal in pre-1990 homes can add $5,000–$15,000. These are non-negotiable in New Zealand.
How to Reduce Costs Without Cutting Corners
Get three quotes minimum. Specify products yourself rather than letting trades supply them. Phase the renovation if cash flow is tight — tackle bathrooms first as they add the most value per dollar spent.
