The 32-year-old met youngsters, their families and nursing staff at a play therapy session as part of the royal tour in New Zealand, which began 7 April with husband the Duke of Cambridge plus their son Prince George and a hefty entourage.
After being greeted by Mayor Julie Hardaker at Hamilton Airport that day and later crowds outside the venue among sunshine ans showers, the brunette bonded with kids who are experiencing grief, serious illness or the death of a loved one for a Mad Hatter's tea party held inside a giant teepee. There guest were met by characters in the likeness of Alice in Wonderland.
As well as coming face-to-face with key roles from the fictional tale, such as the White Rabbit and Alice, the Duchess was surrounded by fun children’s treats such as jellied eyeballs, huhu grubs, flower pots of sweet chocolate mud and chicken pops.

Kate told members of the crowd later on that William wasn't the biggest fan of her outfit that day. Bev Hayes, 68, said about Kate :"I complemented her on her green dress. She said she liked it but William thought it was a bit bright."
It was her first official engagement without her spouse since they started their overseas trip. The British royals have spent time away from their eight-month-old boy though to experience a boat race and World War I aircraft.
