Water quality information
LAWA shows the best available water quality information to help you decide where to swim. The water quality of swimming sites in the Auckland region is predicted using models. The models use current environmental conditions such as rainfall, wind and tides to predict the current levels of faecal indicator bacteria (FIB) in the water. The water quality status is also updated when unexpected events such as sewage spills are detected, so you have the latest available information.
Predicted risk status
The latest predicted result is checked every 15 minutes so you can see the current water quality status for this site.
Heavy rain flushes contaminants from urban and rural land into waterways and we advise you not to swim for 2 – 3 days after heavy or prolonged rain – even at sites that generally have good water quality. Check that the water is clean and clear before taking a dip.
There has been significant rain since this site was last sampled. This may have affected the water quality at this site.
What do the icons mean?

Site suitable for these activities and has these facilities
Our lakes, rivers, and beaches are great natural playgrounds but they can be unpredictable. Be aware of other potential risks such as rips, strong currents, sudden drop offs, or underwater objects before jumping in. LAWA recommends that you avoid swimming for 2 - 3 days after heavy rainfall and follow the advice of any warning signs in place.
From Maraetai the shoreline stretches for several kilometres of splendid unspoilt coastal scenery along the narrow Coast Road until it reaches Umupuia, also known as Duders Beach. Opposite the beach is Umupuia Park, a Maori cemetary and marae – the meeting place of the Ngai Tai people.
The Duder family have farmed in this area since 1866. The original homestead, Rozel, is named after a house on the Channel Island of Guernsey, where Mrs Duder had lived as a child. Umupuia is the heartland of Ngai Tai, the tangata whenua (indigenous people) of this part of the Pohutukawa Coast.
Along the coast many of the once plentiful Ngai Tai pa and settlement sites are still visible. On the eastern headland of the bay(now Duder Regional Park) is the traditionally important pa, Wharekaiwhara
