Whetū is also used as a masculine name in Maori. However, it's more common for females. So, I think that the "Gender" of this name should be changed from "Feminine" to "Feminine & Masculine". Some evidence for this is that Whetū is also used as a name element in unisex and masculine Maori names. Some known male bearers of this name are Whetu Taewa (a New Zealand former professional rugby league footballer who represented New Zealand six times between 1989 and 1996), Whetu Douglas (a New Zealand rugby union player who currently plays as a loose forward for Canterbury in New Zealand's provincial rugby competition the Mitre 10 Cup), and Whetu Henry (a New Zealand former rugby league footballer who represented New Zealand in the 1977 World Cup).Sources: https://forebears.io/x/forenames/whetu https://en.m.wikipedia.org/wiki/Whetu_Douglas https://en.m.wikipedia.org/wiki/Whetu_Taewa https://en.m.wikipedia.org/wiki/Whetu_Henry [noted -ed]
