TThe princess, a diplomat, called the visit of Harry and Meghan the "maximum diplomacy."
Outside the couple they were given a Taovala, an apron-shaped skirt, added over a dress or pants, which means that Tongan respects the higher ranks.
They met local merchants and artisans from Tonga while the group of singers and dancers from Masani performed music and songs from the island. Harry seemed to make a small template when the music started.
They were given a picture of the Royal Tongan motif, Fata O Tu'i Tongan.
Uili Lousi, artist and artisan, said: "They said they would put it in their house."
Earlier, the Duke of Sussex said the entertainment at an official welcome reception was "very good" when he met with the Tongan prime minister.
Harry and Meghan, wearing a Martin Grant dress, were greeted by more than 50 public officials dressed in red and black shirts and traditional costumes as they entered the government buildings of St. George for a meeting with Prime Minister Akilisi Pohiva and his cabinet. .
