Disgraced National backbencher Claudette Hauiti ranks among the highest spending MPs in Parliament over the last quarter.
Ms Hauiti, who's retiring at September's election after misspending taxpayers' money, spent $30,824 on travel and accommodation from April to June. That compares to between $15,000 and $20,000 by other Auckland-based National backbenchers.
Mana leader Hone Harawira holds on to his title as the highest-spending MP, racking $52,845 - more than twice that of Labour leader David Cunliffe, who spent $24,154.
However, Mr Harawira's Te Tai Tokerau electorate is one of the largest in the country and can be expensive to traverse.
Other big spenders include Maori Party leader Te Ururoa Flavell ($37,226), Labour's Damien O'Connor ($33,013) and New Zealand First's Richard Prosser ($31,318).
Meanwhile, details of Ministers' credit card spending have also been released.
As usual, Prime Minister John Key sits top of the list, spending more than $65,000 on travel and accommodation from April to June, followed by Maori Affairs Minister Pita Sharples who claimed almost 46,000.
