This was particularly important for Māori, Lifewise chief executive Moira Lawler said.
Māori make up 59 per cent of those helped by Housing First, while 21 per cent have Pacific heritage.
"Listening to the expertise of those who have lived experience of homelessness is a key element of getting this right for Māori," she said.
The latest figures come as Housing First's founder, Canadian psychologist Sam Tsemberis, gets set to visit New Zealand tomorrow on a one-week workshop tour across the country.
When Tsemberis last visited, the Housing First model had been operating in Hamilton for some years but was just starting in Auckland.
However, its success since then has led the Government to adopt it as the major tool to tackle homelessness across the country.
It is now being rolled out to Tauranga, Christchurch and Wellington as well as regional centres.
In each city, the programme will be run by a collection of support groups run backed by Government funding and agencies, such as the Ministry of Social Development.
In Hamilton, the collaboration of support groups running Housing First is called The People's Project and has helped 902 homeless adults and children into rental homes since September 2014.
Last month, The People's Project began the country's third Housing First programme in Tauranga after the Government selected them to deliver it.
Housing First programmes also planned to kick off this year in Christchurch and Wellington and Lower Hutt with the goal of housing up to 100 and 150 homeless in each area.
Regional Housing First programmes aiming to house 550 people between Rotorua, Whangārei, Nelson and Napier-Hastings are also close to getting off the ground.
They are being funded by a $64.3 million Government package announced in February.
The package will also help extend Auckland's pilot two-year programme, which was initially jointly funded by the Ministry of Social Development ($3.75m) and Auckland Council ($1m).
For Lifewise's Lawler, that's just part of the start of a wider strategy that should also address housing affordability and increase support services for those in need.
"We need more permanent housing and more wraparound support so people don't end up back on the streets," she said.
"Let's not forget that homelessness is a symptom of a larger issue of income disparity and poverty."
