Details of the couple's 12-day tour Down Under were released this morning (NZT).

Charles and Camilla will arrive in Wellington on November 4 and travel to Dunedin, Nelson, Ngaruawahia, New Plymouth and Auckland, before heading to Australia.

They will be welcomed to Turangawaewae Marae, the home of the Kingitanga or Maori King Movement, where they will view a waka armada of canoes on the Waikato River.

They will also travel by train into Dunedin station and, to mark Conservation Week in New Zealand, visit the Orokonui Eco-Sanctuary - home to some of New Zealand's rarest birds, reptiles and plants in the most protected forest in the South Island.

They will lay a wreath at the National War Memorial in Wellington and Charles will take part in a military exercise in Westport.

Heir to the throne Charles, who will one day be head of state of both countries, will meet Australia's latest prime minister Malcolm Turnbull on Remembrance Day in Canberra on November 11 and it could prove to be an interesting encounter.

Mr Turnbull, who is Australia's fourth leader since 2013, was once the public face of the country's republican movement.

But in recent years, the popularity of the Duke and Duchess of Cambridge and their children has dampened enthusiasm for replacing the monarch with a president, with Prince George being dubbed the "republican slayer" after proving a hit with the Australian public.

Charles will celebrate his 67th birthday on November 14 with a traditional Aussie barbecue near a Perth beach.

It is the Prince's ninth visit to New Zealand, and his 15th to Australia and Camilla's second to both countries. The couple last visited New Zealand and Australia in 2012 to mark the Queen's Diamond Jubilee.

The couple will fly to and from Singapore via scheduled flights, but onward and other flights will be with the Royal New Zealand Air Force and the Royal Australian Air Force.
