Taxpayers will stump up $30,000 to put in a set of double doors to separate opposing MPs in Parliament, it has been confirmed.
Parliamentary Service said this morning that the cost reflected the fact the new doors had to be in keeping with the heritage features of Parliament House.
Labour and National Party MPs have offices near each other on Parliament's second floor.
National MP Judith Collins started a war of words between the parties yesterday, tweeting that it was sad that Labour had insisted on the measure that she had been told would cost $50,000.
Labour's chief whip, Chris Hipkins, fired back, pointing the finger at National for proposing the doors be put in.
