Borrowed from Maori. The etymology is disputed. The first syllable is probably from Proto-Eastern Polynesian *wai (“water”), from Proto-Nuclear Polynesian *wai, from Proto-Polynesian *wai, from Proto-Oceanic *waiʀ, from Proto-Eastern Malayo-Polynesian *waiʀ, from Proto-Central-Eastern Malayo-Polynesian *waiʀ, from Proto-Malayo-Polynesian *wahiʀ. Maori toreke (“be left behind, forsaken”) can be found in dictionaries.
