The wise thing for the Prime Minister to do is ask Gerry Brownlee to hand in his transport warrant and to stand him down for the duration of the CAA investigation, says Labour Leader David Cunliffe.

'It's not good enough for the minister to delegate the aviation portfolio to the associate minister. It's just not on to continue as Transport Minister while being investigated by transport officials.

'National ministers have to realise they are not above the law. All New Zealanders expect this investigation to be carried out without fear or favour.

'Mr Brownlee must face the consequences of his actions like any other New Zealander. Similar security breaches overseas have seen entire airports evacuated.

'The Prime Minister must surely realise it is unwise for the Transport Minister to continue in his position."
