After major reclamation works along the Auckland waterfront, many of the beaches residents had traditionally used for bathing in the 19th century were no longer accessible.

During this period, pipes were installed to better fill the baths with seawater, however the sanitation plant at Ōkahu Bay caused the water quality to worsen.
