Tuvalu at the Pacific Games similarly rotated on a four-year basis in the intervening years between the main games. A combined Gilbert and Ellice Islands team participated at the 1963, 1966, and 1971 South Pacific Games. An athlete from Tuvalu (then Ellice Islands), namely Nelu Arenga, is at least documented for 1971. Athletes from Tuvalu attended the 2003 South Pacific Games for the first time.

Tuvalu competed at the 2007 Pacific Games in Apia, Samoa.
Geology of the Pacific Ocean Geology of the Pacific Ocean The Pacific Ocean evolved in the Mesozoic from the Panthalassic Ocean, which had formed when Rodinia rifted apart around 750 Ma. The first ocean floor which is part of the current Pacific Plate began 160 Ma to the west of the central Pacific and subsequently developed into the largest oceanic plate on Earth. The tectonic plates continue to move today. The slowest spreading ridge is the Gakkel Ridge on the Arctic Ocean floor, which spreads at less than , while the fastest, the East Pacific Rise near Easter Island, has a spreading rate of over
