The expenses of former Waikato District Health Board chief executive Dr Nigel Murray show he spent more than $218,000 of taxpayers' money in three years.

Waikato DHB finally released the figures after Murray resigned last month, ending a two-month investigation into his spending.

The figure includes $50,000 for his relocation from Canada to Hamilton to take up the $560,000 a year role in July 2014.

That amount was double the agreed $25,000 to fly him to New Zealand and ship his household effects.

The chief executive who preceded Murray, Craig Climo, spent $17,000 over two years.

Murray's spending also covered a whopping six months' accommodation, about five months more than what is usually paid for by taxpayers.

Under all other expenses in 2016/17, receipts show Murray bought a mobile phone and iPad, usually provided by the DHB, at a cost of $7874.24.

It's unclear yet if the hundreds of pages of receipts spanning the three years show whether Murray used public money to pay for the travel and accommodation of two Canadian women, which the Herald understands was discovered during the course of the independent inquiry.

However expenses from 2014 for "early arrival" accommodation show costs for two adults. The Herald understands the other woman was not Murray's wife of 31 years, Nicola Murray.

The DHB said it could not release the information due to privacy.

"In this case, the investigation report is in draft form. It was presented to Dr Murray but it does not take into account Dr Murray's views (if any) on that draft," the DHB said in an open letter on its website.

"We are therefore concerned that the release of the document would encroach on Dr Murray's privacy, the confidential nature of the employment relationship and thereby interfere with procedural fairness."

The board accepted Murray's resignation on October 5 on the basis he pay back all outstanding amounts.

The DHB today said Murray had paid back $30,000 since May 18 this year and that he now owed less than $50,000.
