Prime Minister Jacinda Ardern says Prince Harry and Meghan Markle's royal visit to New Zealand could cost taxpayers around $1 million, using past royal visits as a rough guide.
The dates for the royal tour were revealed last night to be October 28 to November 1.
Ms Ardern believes the benefits to the New Zealand economy will be worth the cost.
"At this stage we have had very rough estimates and once we are through the planning we will have a better guide. There are benefits to New Zealand for these visits and we will be looking to maximise them.
"The rough guides we have had in the past for a royal visit have tended to be around the $1 million mark," Ms Ardern said today.
She says the exposure from international media around the royals visit will be beneficial to the country and hopes that the Duke and Duchess of Sussex have a "special" time here.
The Duke and Duchess will arrive in Wellington on Sunday October 28 and will visit Abel Tasman National Park the next day.
They will visit Auckland on Tuesday October 30, and Rotorua the next day, before departing the country on Thursday November 1.
The couple will also visit Fiji then Tonga.
Further details regarding the itinerary will be released closer to their arrival.
