The Governor-General will represent New Zealand at the funeral of the Saudi King Abdullah.
Sir Jerry Mateparae will travel to Saudi Arabia for the ceremony of condolences for King Abdullah bin Abdulaziz Al Saud, who died on Friday local time, aged 90.
"[Sir Jerry] will join Heads of State and dignitaries from many countries at the ceremony, and expects to tender condolences on New Zealand's behalf on Tuesday," the Governor-General's office said.
World leaders have already begun arriving in the country to give their condolences to the nation on the death of King Abdullah, who ruled Saudi Arabia for 20 years.
Despite deep tensions and rivalries between the nations, Iran's Foreign Minister Mohammad Javad Zarif was among the first to arrive to the kingdom on Saturday, where he was greeted at the airport by the late king's son, Prince Turki, the Associated Press said.
