During their stay, the British media were taken for a night-time tour of Hobbiton. Several also took up the offer of a jetboat ride on the Shotover after the royal couple had their ride in Queenstown.
Despite the rain during much of the visit, many of the royal reporters have been tweeting about those experiences and were particularly taken by Queenstown. Mr Key has defended the $1.2 million cost of the visit, saying the benefits of it far outweighed the cost.
Numbers of tourists from Britain have dipped in recent years because of the global recession and because of new departure taxes, which have now been reduced.
Mr Key said the royal visit had been positively received throughout the country.
"For many, it has been the chance of a lifetime to catch a glimpse of the royal couple. I've seen first hand how much it has meant to people, young and old, to be part of the generous Kiwi welcome."
The royal family will have tomorrow off before ending their visit with engagements in Wellington on Wednesday. They leave on Wednesday afternoon to travel to Australia with a lot of excess baggage after receiving a multitude of gifts on their stay.
