Ōrākei Basin: A Volcanic Gem in Auckland
Ōrākei Basin, located in the central Auckland suburb of Ōrākei, is a fascinating volcanic feature just southeast of Downtown Auckland. This 83,000-year-old crater is one of the 53 volcanic maunga and craters in the Auckland volcanic field. With a diameter of 700 metres, it is one of the widest explosive craters in the region. The surrounding tuff ring, particularly prominent on the south side, rises steeply up to 40 metres high. Ōrākei Basin is also one of the most centrally located parks in the city where you can experience native bush.
A Historical Transformation
Originally, the crater was a freshwater lake and swamp. However, at the end of the last ice age, the sea level rose by about 90 metres, causing the Waitematā Harbour to encroach on the lake, transforming it into part of the Hobson Bay tidal lagoon. In the 1920s, a causeway with a control gate was built on the north side to support a railway line. This construction separated the lagoon from the basin, effectively recreating the lake while allowing it to be flushed and refilled as needed. The east end of the basin features a scenic inlet surrounded by houses and bush.
Recreational Activities and Scenic Walks
Ōrākei Basin is popular for water recreation, including water skiing. However, the highlight for many is the walking loop around the basin. This loop includes a long boardwalk above the lake on the north side and a curved bridge over the inlet. The walk then ascends onto the crater edge, offering views back to downtown Auckland.
Along the way, you'll pass through short sections of native forest before continuing the walk around the lake's edge on the south side. Keep an eye open for the shags near the curved bridge.
How to Get There
Ōrākei Basin is accessed from Orakei Road, between Kepa Road and the intersection with Shore Road and Upland Road, about a 10-minute drive from the central city. Take the signposted access road and note that the access road is narrow in places. The main car park is located at the end of this road.
From here, it is a short drive to Tamaki Drive and the beaches of the Eastern Bays, including Mission Bay, Kohimarama and St Heliers.
