Tawharanui Regional Park is New Zealand's first open sanctuary. It was converted from a private farm to a regional park in 1973. As an open sanctuary, it encourages conservation of native plants and animals while being mixed with an organic farm and public recreational space. It is home to kiwi's, dotterel, pateke, kakariki, bellbirds, robins, kaka, whiteheads, sheep and cows. This beautiful sandy beach is one of the most popular surfing spots around Auckland.

Amenities include campgrounds, toilets, picnic area, water, pram access, parking, ranger office and contact phones. Limited mobility parking, toilets and paths are available.

This beach has received a special status of green. The area is no longer monitored due to its history of excellent water quality.

SOURCE INFORMATION

Safeswim uses predictive modelling to provide the public with real-time water quality and safety information. Predictive modelling allows Safeswim to forecast recreational water quality so that bathers and other recreational water users have better access to the current and future status of their beaches. This allows recreational water users to make better, more informed decisions about when and where to get in the water. Water quality predictions are made using statistical modelling. Models include historical and current water quality test results, as well as other environmental factors such as wind, rain, tides, and sewage events like CSOs. Safeswim’s models are updated every 10 minutes, and display results using 3 risk categories:

People are exposed to very low risk of infection from contact with the water. The beach’s water quality doesn’t present an immediate health risk to those in direct contact with it.

People are exposed to a low to moderate risk of infection from contact with the water. This is the minimum acceptable state. The beach’s water quality still meets an acceptable standard for swimming.

People are exposed to a moderate to high risk of infection from contact with the water. The beach’s water quality is considered unsuitable for swimming.

Swim Guide interprets these categories in our pass/fail system as:

Very low risk and low to moderate risk categories receive a GREEN/PASS in Swim Guide.

Moderate to high risk categories receive a RED/FAIL in Swim Guide.

The predictive models use New Zealand’s Ministry of Health and Ministry of the Environment’s Microbiological Water Quality Guidelines for Recreational Water. The Guidelines are:

Marine water : Single sample value > 140 Enterococcus / 100 ml
Freshwater : Single sample value > 260 E.coli / 100 ml
