Kate Middleton seemed to have her most happening fashion moment of the royal tour on Sunday.

The Duchess of Cambridge, who is on a 19-day official visit to New Zealand and Australia along with Prince William and Prince George, had three dress changes on 13 April. She is expected to have over 30 dress changes throughout the trip.

On their seventh day in New Zealand, William and Kate carried out a number of engagements in Dunedin and Queenstown.

The royal couple indulged in Kiwi activities including rugby, New Zealand wine tasting, boat rides and traditional Maori welcome.

Apparently, the 32-year-old Kate wore different outfits for all her engagements through the day.

In Dunedin

Kate opted for a turquoise Emilia Wickstead dress to start her day in Dunedin, which is the second-largest city in the South Island of New Zealand, and the principal city of the Otago Region.

Their Royal Highnesses arrived at Dunedin airport, where they were greeted to a formal as well as a traditional Nagi Tahu welcome.

The Duke and Duchess then attended a Palm Sunday church service at St Paul's Cathedral in Dunedin.

Kate looked formally dressed in her outfit and Jane Taylor hat for her initial engagements in Dunedin.

The Duchess switched to strikingly contrasting casual getup as she coached young players at Rippa rugby tournament held at Forsyth Barr Stadium in Dunedin later in the day. Kate wore a Jonathan Saunders jumper, skinny jeans and Mint Velvet pumps for the event.

In Queensland

On the seventh day, William and Kate also visited Queensland where they took a tour of Amsfield Winery and took jet-boat ride on the Shotover River.

For both the occasions, Kate was casually dressed in a white and blue check shirt over dark leggings.

She wore pumps during the boat ride and her four-inch tall wedges while taking a walk around the vineyards. At the winery, the Duchess also wore her navy blazer, which she wore on the fifth day in New Zealand.

The royal couple's official tour of New Zealand, representing The Queen who is Head of State, has ended. The royal family will retire privately for a day before arriving in Sydney on 16 April to kick start their second and last leg of royal tour.
