The property industry is aiming to develop a long-term plan to address housing issues which transcend the vagaries of three-year political election cycles.
This week's Property Council residential development summit will bring together international and local experts, politicians and others to consider a a range of topics including social housing, build-to-rent and urban development, including infrastructure and community services.
Council chief executive Leonie Freeman said the industry was looking at how innovation and sustainable development goals could be used to improve large-scale residential housing.
"There are some amazing people doing fantastic things and you know part of our thing is by holding conferences these people get to profile some of this and make people more aware, because it is about this collective change, isn't it. We're all a part of it," Freeman said.
The sector, which included industry, government, iwi and other groups, needed to work together to address critical housing shortages, particularly in Auckland, she said.
"We need to build 15,000 houses a year in Auckland, half of which are affordable. We need to get homeownership to 65 percent, including Māori and Pasifika. We need to make sure that at least 95 percent of our existing houses are warm and safe and dry. We need to end homelessness in our city. We need to have a zero waitlist for social housing and we need to strengthen communities."
A collective approach would work better than the fragmented approach currently in place, she said.
"People are doing some fantastic work right across the whole housing continuum, and everybody involved, but it's not joined up and I think this is the one shift that we need to make, and it's worked overseas," Freeman said.
"This collective impact approach has actually worked to solve some really complex, large scale seemingly intractable social problems. So yes, I'd like to see it here."
The one-day summit takes place at the Aotea Centre in Auckland on Thursday.
