Baddeleys Beach-Campbells Beach

Baddeleys Beach and Campbells Beach are a contiguous settlement on adjacent beaches on the southern side of Tāwharanui Peninsula in the Auckland Region of New Zealand. The beaches are on Millon Bay, which is a part of Kawau Bay.

The land around Millon Bay was originally covered by kauri and other native trees, which were the focus for logging by early European settlers. Once the land was cleared it was used for dairy farming by the Baddeley and Campbell families. In the mid-1960s, with farming proving financially marginal, blocks were sold off for the building of baches. These subsequently were upgraded to or replaced by permanent dwellings.

Baddeleys Beach Reserve and Campbells Beach Reserve give public access to the beaches at each end of the settlement and provide basic amenities.
