Big Bay Bach at Sadler Point, Mahurangi Regional Park (East)

Big Bay Bach is on the eastern side of the peninsula that encloses the Mahurangi Harbour.

It is in a clearing surrounded by cabbage trees and pōhutukawa, and is close to a beautiful sandy beach. The perfect spot to walk, kayak, boat or relax.


Help protect our kauri trees

We have closed large sections of our parks network to prevent the spread of kauri dieback.

When you visit our parks you need to clean your footwear and equipment to avoid transferring disease from one area to another. For more information see Protect our kauri trees.

Accessible by water only

There is no vehicle access - you must have a water craft appropriate for coastal boating (boat, kayak, etc.).

All campgrounds, baches and lodges are closed.

All bookings for accommodation will be cancelled up until 30 April. We will be processing full refunds for these bookings.
