Ms Adams, whose mother was Tongan, chose to make Tonga the first island nation she visits in her role as New Zealand's Pacific Sports Ambassador, aimed at promoting healthy lifestyles and encouraging participation in physical activity.
At a reception in Nuku'alofa she said she knew she bore a big responsibility to encourage and inspire Tongans to take part in the games.
Ms Adams says the 2019 Pacific Games should be an exciting time for Tonga.
