Orewa SLSC was formed in 1950 by members of Milford SLSC which had fallen into recess. At this time the Estuary outflow travelled north along the beach and ended about where the club now sits. This made the beach quite dangerous and was the reason that the club is sited where it is. In the late 1950s the Air Force bombed the channel in the Estuary and this changed the river out flow straight out to sea.
Clubbies originally stayed in a tent in the camping ground and later built a small shed about where the public toilets are to the south of the Club. The first proper clubhouse was opened in 1960.
Over the years the Club has performed over 1100 rescues in addition to countless other actions
