Kate and William continued their official tour of Australia and New Zealand with a banquet held at Government House in Wellington on Thursday (10 April).
The dress worn by Kate featured hand-stitched silver beading in the shape of a fern, which was to represent New Zealand's national emblem.
William gave a speech during the evening, where he joked about the couple's eight-month-old son George, who has joined them on their first overseas visit to Australia and New Zealand as a family.
"Thank you for hosting Catherine, George and me during our time in New Zealand," he said. "I hope that George doesn't keep you up, he has been known to be particularly vocal at 3am and I swear I heard him doing the Haka this morning."
Sport-loving William also got a cheer when he suggested his son was already being prepared for life on the rugby pitch: "He's a bonny lad and you'll be pleased to know that he's currently preparing for life as a prop forward."
During the event, a new portrait of William's grandmother Queen Elizabeth II was unveiled.
Earlier in the day, royal couple William and Kate had paid their respects to New Zealand's war dead by laying wreaths at a memorial and wearing poppy pins on their jackets. They also visited a Great War exhibition at Omaka Aviation Heritage Centre owned by Lord of the Rings director Peter Jackson.
Thousands of royal fans lined the streets today for a glimpse at the popular couple, who took time to chat with them and accept gifts on behalf of their baby son, who was back at Government House with his nanny.
George took part in his first-ever public engagement yesterday, joining fellow babies at a Wellington playgroup.
