The Labour Party says it will not support a proposed change that could make it easier for Wellington-based MPs to claim extra accommodation allowances.
The Parliamentary Services Commission is considering a change that would allow those MPs to nominate a home base away from Wellington.
That would mean MPs who live in in the capital with their family could claim out-of-town expenses for that home.
Labour leader Phil Goff says the proposed change is neither desirable nor necessary. He says his party has registered its opposition, but believes the Government will proceed regardless.
The Greens say the present rules fairly reimburse MPs who have to spend a lot of time in Wellington, and no change is needed.
But Prime Minister John Key says the point of the proposed change is not to make it easier to claim accommodation expenses.
