The Duke of Cambridge was accompanied by Prime Minister Jacinda Ardern in Auckland, where he laid a wreath on behalf of his grandmother Queen Elizabeth II on the national day of remembrance, which commemorates all Australians and New Zealanders "who served and died in all wars, conflicts, and peacekeeping operations".
Ardern spoke of Prince William's visit, noting that it will "bring comfort to those affected".
