National MP Judith Collins tonight released emails that show a $30,000 door that will separate Labour MPs from National MPs sharing a floor in Parliament House was opposed by the National Party.
She and six other National MPs were consulted about the door by National senior whip Tim Macindoe in January this year.
Mr Macindoe's reply her and the six other MPs he consulted says: "I have now heard from all of you in response to my request for your thoughts about installing an extra security door on Level2 and I'm pleased that you are all of the same view...Thank-you for replying and for the helpful reasons you provided for not wanting the door."
Mr Macindoe said he had told Jim Robb, the Parliamentary Service group manager of precinct services, that National wanted to the status quo to be maintained.
Labour whip Chris Hipkins said yesterday the door had been proposed by National MP Gerry Brownlee after last September's election, but omitted to say parties had been consulted in January to say whether they really wanted it.
