Motukorea / Browns Island is a small volcanic island in the Hauraki Gulf, roughly 3 kilometres off the Tāmaki Estuary. The 60-hectare island forms part of Auckland’s regional parks network and offers walking tracks to a scoria cone, crater, Māori pā sites and historic ruins. Access requires private boat, kayak, water taxi or charter, which helps keep visitor numbers low. The island became Auckland’s newest regional park and its first island public reserve in February 2018.

About Motukorea / Browns Island
Motukorea / Browns Island is one of more than 50 islands in the Hauraki Gulf Marine Park. It ranks among the best-preserved volcanoes in the Auckland Volcanic Field, featuring a prominent scoria cone, deep summit crater and remnants of a tuff ring visible in coastal cliffs. The highest point reaches 68 metres and offers views across the gulf toward the Auckland isthmus and, on clear days, the Coromandel Peninsula.
The island erupted approximately 24,500 years ago. Successive phases produced the tuff ring, lava flows and the final scoria cone. The crater remains well-defined, providing a clear example of volcanic landforms in the region.
Motukorea contains numerous Māori archaeological sites, including three pā with earthworks, terraces, pits and middens that reflect long-term occupation. The name Motukorea refers to the oystercatchers (tōrea) once common on the island. European history includes maritime activity, with visible remains of paddle steamer structures on the shore.
The Volcanic Landscape
The walk from Crater Bay to the summit takes about 25 minutes across open farmland. The crater forms a genuine volcanic depression rather than a simple hilltop, and its scale becomes apparent at the rim. This vantage point helps visitors understand the inner Hauraki Gulf geography and the island’s position relative to nearby volcanoes such as Rangitoto.
Māori Archaeological Sites
The island holds one of the more significant archaeological landscapes in the Auckland region, with dozens of recorded sites. Three pā occupy parts of the scoria cone and surrounding slopes. Walks of up to 90 minutes pass earthwork remains, cultivation areas and middens that illustrate pre-European settlement patterns.
Paddle Steamer Ruins
A 30-minute walk from Crater Bay leads to the remains of paddle steamer structures on the shoreline. These remnants recall the era when steam vessels serviced settlements around the Hauraki Gulf. The site adds a layer of maritime history to the island’s natural and cultural features.
Getting There
No scheduled public ferry serves Motukorea. Visitors reach the island by private vessel, sea kayak or arranged water taxi or charter from Auckland marinas. Guided kayak tours operate from launch points near the Tāmaki Estuary, with the crossing taking roughly 45 minutes in suitable conditions. Landing occurs at the sheltered Crater Bay beach on the western shore, which suits small boats and kayaks when the sea is calm.
What Visitors Often Say
The island feels remote despite its proximity to Auckland. The crater is impressive and well-defined, with excellent views back to the city and out to the Coromandel. Kayaking over from the Tāmaki area, spending several hours walking the tracks, and exploring the ruins makes for one of the better day trips from the city.
