Prince William signed the book of remembrance whilst a Didgeridoo played and a Māori waiata (song) was performed by London-based Ngāti Rānana.

"We now take the opportunity on Anzac Day to commemorate all Australians and New Zealanders who made a contribution not just in Gallipoli, but throughout those conflicts," Smith said.

"The day of commemoration has also grown to acknowledge not just the contribution made by those millions of men and women, but also to reflect upon the values and virtues of character of diversity.

"We have grown throughout that period of time, and now come to reflect the values and virtues and characteristics of both Australia and New Zealand."

There will also be a wreath-laying ceremony at the Cenotaph in central London, led by the Duke of Gloucester.

This will be followed by a Service of Commemoration at Westminster Abbey.
