UPDATED 5.57pm The leaking of details about a police investigation into the chairman of a Mangere marae is a smear after his work to help the homeless, a marae spokeswoman says.

Social Housing Minister Paula Bennett has this afternoon phoned and apologised to Te Puea Marae chairman Hurimoana Dennis, a police inspector and iwi liaison officer.

A member of her staff told a journalist that Mr Dennis was under police investigation.

Marae spokeswoman Moko Templeton told the Herald that Mr Dennis had the full support of the marae board. She felt the leaking of the details about Mr Dennis was a smears.

Opposition parties have said revealing the police investigation is an example of dirty politics and a sacking offence – but Mrs Bennett says the staff member assumed the information was in the public arena.

“My staff member very much regrets this error and has apologised to me and I accept their assurances it won’t happen again. I have made it clear that it was not appropriate,” Mrs Bennett said in a statement.

“I have called Mr Dennis to offer my apologies in person.”

Labour's housing spokesman Phil Twyford said it was unthinkable that Mrs Bennett’s press secretary would go “rogue”.

“Political staff would not take such serious unilateral action without the knowledge of their Minister. Their job is to act in the best interest of their boss.

“This is another example of Paula Bennett lashing out under pressure and embarking on a character assassination to try to divert attention away from her failed social housing policy. She has a history of vindictive privacy breaches.”

Mr Twyford said if the allegations were true, it was “a disgraceful abuse of power”.

“If this isn’t dirty politics, I don’t know what is.”

Mr Twyford said Mrs Bennett needed to clear up the allegations. If the leak happened and Mrs Bennett was aware of it, she would be “unfit to be a minister”, he said.

NZ First leader Winston Peters said he did not know the details, but if the allegations were true it would be a sacking offence for anyone involved, including Mrs Bennett.

Maori Party co-leader Marama Fox said such behaviour, if true, was “underhanded”.

“I couldn’t even wonder why we wouldn’t be more focussed on trying to get those families into homes rather than muddying the waters with tid bits of information.”

Green Party co-leader James Shaw said the allegations were very serious, and needed to be cleared up.

Green MP Jan Logie wants to see more detail.

But she points out Ms Bennett has a history of leaking information for political gain, referencing an incident in 2009 when the Minister publicly disclosed personal details about beneficiary Natasha Fuller.

Ms Logie is clear on what should happen if the new allegation is true.

"I would expect a resignation from the minister."

Earlier and on her way into question time, Mrs Bennett confirmed that Mr Dennis had told her of the police investigation during a private meeting on Friday.

"I have heard that there is an investigation currently, but I have no idea of any details or anything like that."

Asked if her office had been making unsolicited calls to journalists to let them know about that cafe conversation or the police investigation, Ms Bennett said not that she was aware of.

In a follow-up statement issued this afternoon, Mrs Bennett said she a member of her team had told her they had discussed the police investigation with a reporter, “briefly at the conclusion of a phone call about a work matter”.

“The staff member in question assumed the information was in the public arena.”

TVNZ has confirmed that a One News reporter, based outside of the Parliamentary press gallery, was contacted by a staff member from Mrs Bennett’s office.

On what disciplinary action the staff member involved could face, Mrs Bennett said it was an employment matter and confidential.

Mr Dennis has been contacted for comment, as has Te Puea Marae.

A police spokesman confirmed Mr Dennis was stood down from duties on September 21 last year pending a police investigation.

“Police have nothing further to comment on this investigation at this time.”

Mr Dennis has been leading efforts by the marae to help 27 families and individuals to move to social housing, places in families' homes and motels.

The Manukau Urban Maori Authority has found jobs for several adults, and Whanau Ora services are being offered to all the families.

Ministry of Social Development staff have been working at the Mangere marae since it opened up to receive homeless families last month.

This morning Mrs Bennett made a short visit to the marae. She said she wanted to make sure homeless people were linked to other public services such as education, social work and counselling.
