The Princess Royal, Princess Anne, will visit New Zealand later this month.
She has visited New Zealand a total of eight times, with the latest being in 2008.
It is also the first royal visit since the then-Prince of Wales and Duchess of Cornwall in 2019.
Princess Anne is Colonel in Chief of the Royal New Zealand Corps of Signals, and is travelling here to attend its 100th Anniversary celebrations at Linton Military Camp in Palmerston North.
She will also lay a wreath at Pukeahu National War Memorial in Wellington and rededicate the War Memorial at Cathedral Square in Christchurch.
Prime Minister Chris Hipkins welcomed the announcement.
"It's terrific that Her Royal Highness will be able to connect with past and present members of the Corps and acknowledge the importance of signallers within New Zealand Defence Force operations over the last 100 years.
"I look forward to welcoming Princess Anne back to Aotearoa."
She will be accompanied by her husband Vice Admiral Sir Tim Laurence.
The 72-year-old is the only daughter of Queen Elizabeth II, who died last year, and Prince Philip, who died in 2021.
She gained attention when she accompanied her mother's coffin through the whole journey from Scotland to London, stopping at several places, until her final resting place.
The princess also dropped into a deep curtsy as a sign of respect when her mother's coffin was taken into the Palace of Holyroodhouse - the royal's official Scottish residence.
She paid tribute to her father saying he was her "teacher, supporter and critic" and that he left a "legacy which can inspire us all".
