The Wainuiomata River runs along the northern edge of Richard Prouse Park, offering natural swimming holes popular with local families during summer. Set in Wainuiomata on Wellington’s eastern hills, the park provides easy river access in a sheltered, family-friendly setting well away from the city centre.
The site is monitored for water quality through the LAWA programme, with low health risk reported in dry conditions. Richard Prouse Park itself serves as a community sports ground used for football, cricket and local events.

About the Park and River
Richard Prouse Park is a recreational sports ground in the heart of Wainuiomata, used for football in winter, cricket in summer and a range of community activities.
The Wainuiomata River defines the park’s northern boundary, emerging from the upper catchment in the hills to the west. The river pools are accessible directly from the park via a short walk from the car park through open ground to the riverbank.
The swimming holes form naturally where the river channel shapes the park boundary. In summer the water is shallow enough in places for younger children to paddle, with deeper pools suitable for older swimmers. The riverbanks are grassy and open, making it straightforward to set up a picnic while supervising children in the water.
The Wainuiomata catchment is largely forested, which helps maintain relatively clean water during dry periods. The river’s upper reach flows through the Wainuiomata Water Collection Area, a protected forested reserve managed by Greater Wellington Regional Council that supplies a significant portion of Wellington’s drinking water.
Water Quality and Safety
This site is monitored through Greater Wellington Regional Council’s summer water quality programme. LAWA data shows a low health risk during dry conditions.
As with all river swimming in the Wellington region, avoid the water for at least two to three days after heavy rainfall because run-off from the catchment raises bacterial levels quickly. Check the LAWA site before visiting for current conditions.
Cyanobacteria (toxic algae) can form during hot, dry summer periods. If brown or green slimy mats appear on the riverbed or an unusual smell is noticed, stay out of the water. Warning signs are posted if a confirmed algae advisory is in place.
