Britain's Duke and Duchess of Cornwall are set to tour New Zealand next month.

The royal couple, who haven't visited the country for three years, are set to jet to Taranaki on the North of the island for a six-day trip after they bypassed it during their last tour.

New Plymouth Mayor, Andrew Judd, told "They haven't truly visited the country if they don't come to Taranaki. There's just so much to see and enjoy."

Charles and Camilla's itinerary is yet to be officially announced but details surrounding the trip are due to be released next week by the Department of Internal Affairs.

It's believed the Prince, 66, may even be in the country to celebrate his 67th birthday on November 14.

Meanwhile, the couple's trip comes just six months after Charles' youngest son Prince Harry, 31, flew to New Zealand in May for a short week-long visit.

His eldest son Prince William, 33, his wife Duchess Catherine, 33, and their two-year-old son Prince George also paid a visit to the country in 2014 for a 10-day tour.

However, Taranaki residents haven't received a visit from the member of the royal family since Queen Elizabeth and her husband Prince Phillip stopped by in 1954.
