About us

A proud history dating back a hundred years

Today’s swims have a proud history going back to swims held in the early 1900s at Herne Bay and across the harbour when entrants competed for trophies that are still part of our events today.  

Organised by the Ponsonby Swimming club, the first of these was the Wai-Wai Shield event, which saw entrants swim around moored boats from the city’s cement works to the old Shelly Beach saltwater baths. Later it shifted to a triangular course, still among moored boats, off Herne Bay Road and Sentinel Road Beaches.

First run in 1912, the Malloy Shield event ran from Chelsea to the same Shelly Beach baths, until these were demolished for construction of the Harbour Bridge, when the finish line was shifted to Masefield Beach. 

The swim changed again in 1984 when its direction was reversed to finish at Chelsea. This also marked the beginning of today’s era, when under the leadership of Bert and Mamie Raper Auckland Central Masters Swimming (Inc) was formed and took up the baton of keeping the events going. 

Now run as part of our Watchman’s Island swim, the Wai-Wai Cup and Shield have been presented to the fastest male and female swimmers since 1980. The Malloy Shield remains part of our Chelsea swim, as are the Osborne Cup for fastest female, and the Mazzoleni Cup for first male, dating back to 1939 and 1979 respectively.

The Orca Cup and Chelsea Cups with miniatures are presented to the fastest male and female non-wetsuit in the Chelsea swim. 

Other cups and awards include the Eagle Technology Rangitoto Cup with miniatures presented to the fastest male and female non-wetsuit swimmers.

The Lodi Raos (fastest wetsuit male and female) and John White Cup (fastest non-wetsuit male and female) with miniatures are presented at the Marathon Swim. 

As our swims have evolved so the range of swimmers has widened. There is still fierce competition for trophies between dedicated swimmers. For many others the swims are a personal challenge. Everyone is welcome to swim at their own pace. (Although there is a cut-off after a set time.) 

But whatever sort of swimmer you are the same spirit lives on: volunteers who love harbour swimming organising events for other swimmers who feel the same.
