    The best way to experience the reserve and its inhabitants is to get into the water with them.

    Those with a mask and snorkel can explore the rocks close to shore, while divers can drop onto the reefs further out.


    Tāwharanui’s white sandy beaches and clear waters are great for swimming. The most popular swimming beach is Anchor Bay, where toilets are available. It is also a popular spot for surfing if there's a swell on the east coast.

    Child/family friendly activities

    At low tide the kids can explore the rock pools. If you turn the boulders over to look underneath or pick up any sea creatures, remember to put them back carefully afterwards, otherwise creatures beneath them may die.

    Tāwharanui’s beaches make a great place for a family picnic. The regional park is also a working farm, so children can enjoy seeing the sheep and cows.


    The nearest boat launching ramp to the marine reserve is at Omaha. Boaties are welcome to navigate and anchor carefully in the reserve. Extra caution may be needed in some areas because of the number of divers and swimmers.

    Do not exceed five knots within 200 m of the shore or a dive flag, or within 30 m of any other boat or person in the water.

    Boats can enter the marine reserve after fishing outside its boundaries, but it is recommended that fishing rods are stowed out of sight while visiting the marine reserve. Remember, do not feed the fish or discharge anything into the water.

    About this place

    Nature and conservation

    The area has been off limits for fishing since 1981, but it was only made a marine reserve in 2011. It sits within the much larger Hauraki Gulf Marine Park.

    Its unique feature is geological – greywacke rock is exposed forming huge grey-green rocks. These ancient rocks from the Jurassic period are studded with rare marine fossils.

    Tāwharanui contains extensive intertidal and subtidal reefs typical of the moderately exposed coast of the outer Hauraki Gulf. About 50 species of fish have been recorded in the reserve, which also supports a thriving population of lobster. Bottle nosed dolphins and orcas often visit the area.

    The marine reserve is picturesquely situated alongside sandy beaches and gentle farmland, with some stands of native bush and large regenerating wetlands (outside the reserve).
