The State Services Commission is shelling out up to $50,000 a time to lure top bureaucrats to New Zealand.
The "relocation payouts" are happening more frequently as the commission struggles to fill chief executive positions from the ranks of domestic applicants. The money covers flights, freight, up to eight weeks' accommodation and visa expenses.
The commission refused for a year to reveal details of the payments after the Herald on Sunday sought them under the Official Information Act, but finally complied after a ruling by the Ombudsman's office.
Director-General of Health Kevin Woods, and Education Ministry chief executive Lesley Longstone are among senior public sector bosses recruited from offshore in the past two years.
Woods, who already earns nearly $50,000 a month, will be reimbursed up to a further $50,000 after producing receipts for the relocation expenses. He started work here in early 2011 after running Scotland's public health sector, the NHS, for more than five years.
