A newly-formed alliance is hoping to place housing firmly at the top of the election agenda this year for all political parties.
The Homes We Deserve has the backing of dozens of organisations who want to see a commitment to a renovation programme for at least 200,000 homes.
The alliance says over 300-thousand homes in New Zealand are sometimes, or always, damp and 250,000 had mould larger than a piece of A4 paper.
It says doing up these homes could slash carbon emissions, household bills, create tens of thousands of jobs and improve the health of Kiwis.
Joining to outline their argument is Andrew Eagles from the Green Building Council and Letitia Harding from the Asthma and Respiratory Foundation.
