United Nations Secretary-General Antonio Guterres is making his first visit to the Pacific in five years, taking in Samoa, New Zealand, Tonga and East Timor.
The centrepiece of Mr Guterres' mission will be the Pacific Islands Forum (PIF) Leaders Meeting, being hosted in Nuku'alofa beginning on Monday.
While in Tonga, he will visit sites still recovering from the 2022 tsunami, engage in a PIF dialogue with leaders, as well as hosting bilateral meetings.
