Use a trained professional to install or upgrade your insulation, as even small installation faults can affect its performance.
Having a professional install insulation
Professional installers buy insulation in bulk so they may be able to install your insulation more cheaply than you can do it yourself. We recommend you get more than one quote so you can compare prices.

Installing insulation yourself
If you’re considering the DIY approach, everything you need to know about installing insulation is in the New Zealand Standard NZS 4246:2016 Installing insulation in residential buildings. It's easy to follow with lots of colour pictures, and it's free to download.
As with all DIY projects, there are safety considerations. Make sure you read and follow the Health and Safety advice in Appendix B. If you're not sure, get a professional to install the insulation for you.
Cantabrians insulating during repairs
If you’re a Canterbury homeowner you can now have insulation installed in walls and other areas that have become accessible during the earthquake repair process. There are specific conditions you need to meet, and you’ll need to pay the full cost of having this work done (there is no government funding available).
The process depends on who is managing your repair process.
