I personally think it’s Lee-Wa, primarily because of Ta= Tahu, Ga=Gali, Po=Pohatu, Onu=Onua, Ko=Kopaka, so
Le=Lewa
And another thing in response to @Kahi about the encyclopaedia pronouncation, I have the that exact “updated”) one and while it pronounces it as Ley-wah for one, it’s old (from 2007, and didn’t even finish the entire year of it) and it also showed Turaga Matau as “Turaga Inika Matau”
