The Salvation Army turned down the opportunity to buy state housing from the Government in March, which Mr Piriri brought up this morning.
At the time, Major Campbell Roberts of the Salvation Army said the church organization did not believe "the lives of tenants would be sufficiently improved by such a transfer".
Nor did it have the "expertise, infrastructure and resources to successfully manage any social housing transfer of size", he said.
Iwi would be able to "move social housing into affordable housing," Mr Piripi said. 
"Because we're prepared to co-invest and utilise our own assets and resources to respond to needs.
"If the Government regarded this as an investment and not as an asset sale ... then we are the partner for them."
