A large earthquake has hit in the sea southwest of Tonga, shaking buildings in the capital.
The 7.4-magnitude quake struck 285km southwest of Tonga's capital Nuku'alofa at 5.19am, the US Geological Survey reported.
It was 170km deep and the Pacific Tsunami Warning Center said on its website that no "destructive Pacific-wide tsunami" was expected.
News website Matangi Tonga said the quake shook homes and rattled windows in Nuku'alofa but there was no damage.
In New Zealand, GeoNet reported three quakes in the North Island, the largest being 6.1, however it has since deleted the reports because they were caused by the Tongan quake.
