We're only a quarter of the way through the year, but politicians have already spent $2.4 million on travel expenses.

The Parliamentary expense returns record spending on accommodation and travel for MPs, their spouses, and staff.

Foreign Minister Murray McCully is unsurprisingly a big spender, with more than $111,000 on domestic and international travel so far.

And also not surprisingly, Labour's Kelvin Davis is the highest spending non-Minister, with more than $31,000 racked up so far.

His Te Tai Tokerau electorate is one of the biggest electorates in the country - and is a long way from Wellington.

Meanwhile, the Prime Minister's taste in gifts has been revealed.

Among other things, the spending shows what sort of gifts John Key hands out to world leaders, including a cat calendar from the SPCA, a merino wrap, and a World of Wearable Art book.
