The royal tour of the Duke and Duchess of Cambridge cost the taxpayer more than $1 million.
Figures released by Department of Internal Affairs (DIA) show $1,035,000 of taxpayer money was spent on the visit, the majority on personnel and travel.
Police also spent $61,274 on the visit, mainly on internal travel for its staff.
The Defence Force, which flew Prince William and Kate around New Zealand, was yet to release the cost to it.
The 10-day visit in April was met with strong public support in the eight centres it took in.
In releasing the figures, the DIA said a unique feature of the visit was the worldwide media interest in the couple, with some 120 foreign and 320 domestic media accredited for it.
"The provisional expenditure for the visit of is consistent with the cost of previous royal visits taking into account the duration and itinerary," it said.
It was possible some small costs were yet to be accounted for, it said.

International travel: $102,000
Domestic air travel: $81,000
Accommodation, meals and other travel related costs: $132,000
Vehicle hire: $108,000
