Whangapoua Bay is a beach at the end of Mabey Road on Great Barrier Island, in the Hauraki Gulf Islands. It has a Google rating of 4.9 from 17 reviews, and reviewers mention white sand, a short walk through pine trees and nesting shore birds.
The Department of Conservation page describes a walk to the graves of people who died in the wreck of the SS Wairarapa in 1894. The graves are at Tapuwai Point, at the north end of the beach, and at Onepoto, at the south end of Kawa Road, and both sites have white picket fences. The page says dogs are not allowed, and other pets must follow conservation land rules.
For a quiet visit with a piece of shipwreck history on Great Barrier Island, Whangapoua Bay is worth the trip, as long as visitors keep to the track.
