The young royals start their 10-day visit of New Zealand in Wellington where they will be greeted by an official ceremony before spending two days in the capital.
They will then travel to Blenheim, Auckland, Cambridge, Dunedin, Queenstown and Christchurch, where they will pay tribute to those who died in the 2011 earthquake.
From New Zealand, the royal party fly to Australia for a 10-day tour of Sydney, Brisbane, Uluru, Adelaide and Canberra starting on April 16.
The visit, which should attract huge crowds eager to catch a glimpse of Prince George who will be nine-months-old when he arrives.
The tour comes 30 years since Prince Charles and Diana, Princess of Wales, visited Australia and New Zealand for six weeks with William when he was Prince George’s age.
It will be Prince George’s first official outing, the Duchess of Cambridge’s first official trip to Australia and Prince William’s first visit down under since 2011.
After touching down in Sydney, the royals first stop will be the Opera House.
The party will then travel across the harbour to Admiralty House where they’ll stay as guests of new Governor-General Peter Cosgrove.
Next day they’ll travel to the Blue Mountains to meet bushfire-affected families.
The region, west of Sydney, is still recovering after major bushfires last October.
The royals then fly to Queensland to plant trees at an RAAF base in Amberley, and also attend a Brisbane city reception.
Returning to Sydney, they will make a stop at Taronga Zoo and its bilby enclosure – named after Prince George as part of the nation’s gift following his birth.
The couple will then visit Uluru, leaving Prince George with his nanny in Canberra.
In Adelaide, the Cambridges will visit the suburb of Elizabeth – named after the Queen in 1955 before returning to Canberra to visit the National Portrait Gallery and Parliament House.
The Duke and Duchess are said to have been busy preparing for the trip and recently hired a new nanny for Prince George for the tour.
The Duchess of Cambridge is also reportedly planning to reveal a high-end designer wardrobe for the trip.
Often lauded for her stylish fashion and high-street choices, Kate’s said to be revamping her wardrobe to feature more designer items with a notably lower hemline.
