From Wellington airport follow State Highway 2 through the Hutt Valley over Rimutaka Hill Road to Featherston. Do not drive through Featherston but once you reach the 70km speed sign you need to take the first hard RIGHT into WESTERN LAKE ROAD. Signpost will also say- Ocean Beach. 40km - follow along Western Lake Road. Stay on the road until you reach a gravel road. Then you will see a large wooden sign on the right hand side - Wharekauhau.
