Porn on expenses of 'red-blooded' New Zealand ex-minister Shane Jones

• Shane Jones

The first public viewing of more than 7,000 pages of credit card expenses booked by former Labour ministers between 2003 and 2008 revealed hundreds of purchases outside the rules.

Former Labour housing minister Shane Jones admitted using his ministerial credit card to pay for "adult movies", blaming it on his libido.

"I'm a red-blooded adult," he said. "It shouldn't have happened – it doesn't make me feel particularly worthy – but I'm not going to hide from it."

He admitted spending thousands of dollars on personal items and called his actions an "egregious lapse".

"It was wrong," he said, adding he had apologised profusely.

He had reimbursed NZ$6,450 (about 3,000) of personal spending on his ministerial card, including the cost of an air charter to take him to a function, before his party lost office in November 2008.

Mr Jones faces a dressing-down by Labour MPs next week, as well as public censure, but does not face further sanctions after paying up.

Former minister Chris Carter bought flowers for his partner's birthday on his ministerial card. Former Maori affairs minister Parekura Horomia spent NZ$500 (230) on one meal at a Chinese restaurant, and former arts minister Judith Tizard bought a NZ$155 bottle of Bollinger with taxpayer cash.

Labour deputy leader Annette King labelled some of the rule breaches "unacceptable".

The Labour Party is not alone in misusing government credit cards. Trade minister Tim Groser of the conservative National Party has charged alcohol purchases of at least NZ$1,470 against taxpayer-funded credit cards since he became a minister 18 months ago.

Mr Groser was subject to censure from the prime minister's office in May after a complaint about heavy drinking among his trade delegation on a flight from the Middle East.

Housing minister Phil Healthy was sacked earlier this year for inappropriately charging wine to his official credit card, but reinstated after the Audit Office found he did not intentionally break the rules.

Prime minister John Key said this first detailed review of expenses spending had set "a new level of transparency in this government".
