Now a regular revelation, the expense accounts show how much they spent on travel, hotels and housing. All of it has to be carefully accounted for.
They are expected to be released tomorrow, just as ministers caught breaking the rules on how they used their credit cards start getting accustomed to living without them.
Cabinet ministers Phil Heatley and Gerry Brownlee apologised yesterday after the Dominion Post highlighted purchases they made last year which they should have covered themselves.
A distraught Mr Heatley told reporters he hadn't known the rules and it was a bad look to break them.
He is going to repay $906.80 in travel, accommodation and meal costs for himself and his family while they were on a South Island visit which included a conference and a trip to Kaikoura's whale watch.
He has paid back $175.30 for food and drinks bought at a National Party conference last year.
Mr Brownlee repaid $151.90 spent in September for a lunch with his electorate staff.
Both have said sorry to Prime Minister John Key, who said he was disappointed by the slip-ups.
Mr Brownlee has given back his card and Mr Heatley says in future his staff will look after his expenses.
Maori Party leader Pita Sharples, who didn't break any rules, said he would probably throw his away.
Some cabinet members don't have ministerial credit cards, including Mr Key and Foreign Minister Murray McCully.
MPs' expenses came under intense scrutiny last year when the first disclosure was made, and some MPs paid back tens of thousands of dollars spent on housing in Wellington and travel for themselves and their partners.
