H, consonant, is pronounced as in English. In the case of a few words the presence of the h does not seem firmly established, while in some words forms are in use with wh for the usual h. With the Whanganui tribe, and some of their neighbours, h is almost entirely wanting, its place being often marked by a break in the word. s of other Polynesian dialects is generally represented by h in New Zealand, and f very frequently so.
