Pohangina Base is a park at 2751 Pohangina Valley East Road in Utuwai, in the Pohangina Valley of the Manawatū. The linked page describes Whareroa Farm, a reserve near Paekakariki on the Kapiti coast, which is a different place, so we have set it aside.
The directory holds no details of what the park offers, its tracks, facilities, access, hours, dogs or children's play, and no visitor comments or figures for other places nearby. So we can say no more about it than its name, valley and address.
