There are currently two Home Insulation programmes on offer to help ensure people are living in healthy homes:
Snug homes:
This completely FREE initiative is open to those who own their home or are privately renting (sorry no Housing NZ homes), and have a Community services card. The application form is quick and easy and is downloadable off their website. You can also call them and they will send you an application with a self addressed envelope.

Retrofit your home programme:
Auckland Council provides a loan scheme for home owners, where you are able to borrow up to $5000 to insulate and heat your home, which is paid back through your rates over 9 years.
