Some 144 jobs will be axed and 339 existing staff will compete for 187 other jobs. This overall cut of 296 will be offset by 130 new jobs, including a new 37-person call centre in Auckland as well as the existing centre in Porirua.
The agency has also axed work in its eight "community renewal" projects in the Auckland suburbs of Northcote, Talbot Park, Wiri and Clendon and in Otangarei (Whangarei), Fordlands (Rotorua), Porirua East (Wellington) and Aranui (Christchurch).
"The corporation will continue to deliver tenancy management services in these areas, but there will be no new funding for community development," it said.
John McCarthy, social services manager for the Methodist Mission's Lifewise agency which looks after Auckland's homeless, said the changes would drive more vulnerable tenants on to the streets.
"The great risk for organisations like us and others working in the area of homelessness and emergency accommodation is that we are going to see more people in Housing NZ poorly supported, which will put more tenancies at risk, result in more evictions and more people coming out of Housing NZ accommodation and potentially more homelessness," he said.
Labour housing spokeswoman Moana Mackey said a Labour Government would reverse the changes and turn Housing NZ back into "a social housing provider rather than just another landlord".
Historian Ben Schrader, who wrote a history of state housing in 2005, said social support became an increasing part of Housing NZ's work as its role shrank from housing low-income workers in the 1930s and 40s to being a "last resort" provider for people such as beneficiaries, those with mental health problems, ex-prisoners and refugees.
But a consultation document issued to staff a week ago says the agency would "stop delivering social services that should be delivered by other organisations".
"Tenancy managers and case managers frequently find themselves following up with many other agencies such as Child, Youth and Family [CYFS] on child safety concerns; district health boards on health; budget services; school truancy issues and so on," the document says.
"The Ministry of Social Development [MSD] will act as a conduit for all other agencies that need to provide social support to the corporation's tenants."
Dr McTurk said all existing Housing NZ branches would be absorbed gradually into MSD's "Community Link" centres, which already bring together Work and Income, CYFS and sometimes other agencies in 50 locations. A further 30 are planned in the next year.
Narrowed focus
* HNZ "will no longer have a role to assist individuals with their wider social needs".
* Tenant calls to tenancy managers will be diverted to a call centre.
* Most tenancy managers will operate from their cars.
* Staff cut by about 100.
