New Zealand First MP Darroch Ball has made a bizarre presentation in Parliament about who might have leaked National Party leader Simon Bridges' expenses.
In an attention-grabbing stunt during the general debate on Wednesday, Mr Ball presented a series of printed out cards with various vehicles and 'suspect' politicians displayed on them.
He compared the cost that two different vehicles would ring up compared to crown limos, then went through his list of "suspects" explaining why they might be behind the leak.

These included National MPs Maureen Pugh, Judith Collins, and Mark Mitchell, former Prime Ministers Sir John Key and Bill English, former National MP Steven Joyce, ACT MP David Seymour - and even Mr Bridges himself.
National MP Scott Simpson spoke directly after Mr Ball, criticising his stunt.
"We know, Mr Speaker, that the primary school teachers are on strike today - what he didn't know was that the primary school students from New Zealand First were in the House today."
National Party leader Simon Bridges' expenses were revealed on Monday after a document was leaked to Newshub political editor Tova O'Brien.
The document revealed Mr Bridges had spent $113,000 on accommodation and travel. Most of the bill was $83,000 on Crown limos.
The leak is now the subject of an inquiry initiated by Speaker of the House Trevor Mallard.
