The real estate agent sacked from Barfoot and Thompson for leaking data on Chinese buyers says he doesn't know how the Labour Party got the information.
Grant Hargrave has confirmed to the New Zealand Herald that he's the agent fired over the information used by the Labour Party to claim foreign buyers are pushing up house prices in Auckland.
The Herald website reports Mr Hargrave said he did not want to be interviewed on this issue.
"I very much would rather not talk about it, I'm sorry," it quotes him as saying.
But he did say he has never spoken to anyone from the Labour Party and had no idea how Labour obtained the information he was sacked for passing on.
"I don't know them. I don't know the Labour people. I honestly just don't know (how the party got it)."
Without naming Barfoot and Thompson, Labour's Housing spokesman Phil Twyford released figures at the weekend showing that between February and April 39.5 per cent of one firm's sales were to people whose last name appeared to be of Chinese descent.
Barfoot and Thompson managing director Peter Thompson yesterday announced that following an internal investigation the company has terminated the contract of a staff member who has breached its policies, resulting in the disclosure of confidential information.
Mr Thompson said confidential data was sent "by the identified internal source to a number of individuals including the media and political figures. However this does not include direct contact with the Labour Party".
Mr Twyford described the sacking as "extremely disappointing".
