Blackhead is a small coastal suburb on Dunedin’s south coast, gathered around a dark basalt headland that runs out into the Pacific. The headland is also known as Makereatu and Te Wai o Tinarau, and it is the reason the suburb exists in this form: a working quarry on the inland side, and protected columnar basalt on the outer coast.
Housing is sparse and largely rural-residential, set back from the cliffs rather than arranged around a town centre. People come for the coastline, including Blackhead Beach and the nearby Tunnel Beach walk, while the quarry remains an active industrial site and is not a public park. The suburb sits inside Dunedin City and is reached by Blackhead Road.

About Blackhead
Blackhead is not a conventional residential suburb with a shopping strip and a school gate. It is a thin coastal district defined by the headland of the same name. The promontory extends about 500 metres into the ocean and rises a little over 100 metres.
East of it the coast is steep, with sandstone cliffs, caves and stacks. West of it the shore drops to lower beaches, and Waldronville sits a short distance away near the mouth of the Kaikorai Stream.
Landscape assessments record Makereatu as an ancient ancestral site and an important stone-gathering place, with wāhi tapu values. A second recorded name, Te Wai o Tinarau, is translated as the waters of Tinarau.
The beach between the headland and the Kaikorai Estuary is also recorded as a place of pre-European settlement. These are cultural values attached to the landform, not a visitor site with interpretation panels or a public marae in the suburb.
Geologically the headland is basalt, a remnant of the long-extinct Dunedin volcano. Its best-known features are columnar joints, often called organ pipes, including formations known as the Roman Baths and the Dock. Quarrying has much modified the inland form of the headland.
The outer columns and coastal habitats are covered by a conservation covenant, agreed in 1991, so that extraction does not take the seaward rock. An Otago Regional Council landscape assessment rates the organ pipes as an outstanding natural feature, while noting that the quarry lowers the value of the headland as a whole.
What remains for residents is a quiet, exposed coastal setting. Most houses sit on land that is elevated or set back from the shore, which coastal-hazard mapping treats as less exposed than the low beachfront further west. There is no local centre.
Everyday shops, schools and community halls are in neighbouring settlements, especially Green Island, rather than in Blackhead itself. The soundtrack of the place is quarry traffic on Blackhead Road, wind off the Pacific, and the working coast.
Getting Around
Blackhead Road is the spine of the suburb. From the city side it leaves the southern suburban street network at Corstorphine and runs past the quarry toward the coast. In the other direction it continues as a narrow rural road toward Waldronville and the Brighton Road corridor. A car is the practical way to live here or to visit.
Public transport does not have a verified stop in Blackhead itself. Department of Conservation directions for Tunnel Beach send bus passengers to the stop at 292 Middleton Road in Corstorphine, then on foot along Blackhead Road and Tunnel Beach Road. That walk is about 1.7 kilometres to the track entrance.
Tunnel Beach Road has no permitted parking, and the council car park at the end of that road is locked outside set hours. Check Dunedin City Council and Orbus before you rely on a bus-and-walk trip.
History and Heritage
The headland’s recorded Māori significance is as Makereatu, an ancestral place used for gathering stone. That value is set out in the Otago Regional Council’s coastal landscape assessment, which also notes kāika (settlement) values on the beach toward the Kaikorai Estuary, and mahika kai values in the estuary itself.
Te Rūnanga o Ōtākou hold mana whenua over the nearby Tunnel Beach coast. Treat the headland as a place with customary importance, not as an informal rock-collecting spot.
European use of the headland has been industrial. Quarrying began in the mid-twentieth century and has continued on the inland portion of the promontory. In the 1980s a proposal to quarry the centre of the headland well below sea level and form a boat harbour was opposed by a local group, the Friends of Blackhead.
The conservation covenant that followed protects the outer rock formations and coastal habitats. The columns themselves are not quarried. The quarry produces basalt aggregate, mainly for road chip, and remains a working site rather than a heritage attraction you can wander through.
Getting Outdoors
This is a coast suburb, not a reserve with a formed network of tracks. Blackhead Beach, in the lee of the quarry, is a known local surf beach. It is not a patrolled swimming beach, and this page is not a surf or swim guide.
Conditions on this exposed south coast change quickly. The western basalt columns can be seen from Waldronville and Blackhead Beaches. The more dramatic seaward formations are difficult and hazardous to reach, and public awareness of them is modest because access is poor.
Do not treat the quarry as a viewpoint or a walking route. It is an active industrial site. Keep to public roads and beaches, and do not cross quarry land or climb the outer columns. Seals and seabirds are sometimes present around the headland; give them space.
For a formed walk, Tunnel Beach is the established option, about 3 kilometres east of the headland, with the signposted turnoff from Blackhead Road. That track is a long, steep descent to a tunnel and a pocket beach, and it is often crowded. The Department of Conservation asks walkers to stay on the gravel track.

Frequently Asked Questions
Is Blackhead a suburb of Dunedin?
Yes. Blackhead is a LINZ suburb inside Dunedin City, on the south coast around the basalt headland of the same name.
How do you get to Blackhead?
Drive Blackhead Road from Corstorphine, or approach from the Waldronville and Brighton Road side. Buses serve Middleton Road in Corstorphine, not a verified stop in Blackhead itself.
What are the Māori names for Blackhead?
Recorded names are Makereatu, translated as to leave a seed, and Te Wai o Tinarau, the waters of Tinarau. Makereatu is recorded as an ancestral stone-gathering site.
Is the quarry still operating?
Yes. Quarrying continues on the inland part of the headland. The outer basalt columns and coastal habitats are protected by a conservation covenant and are not quarried.
Can you walk to the basalt columns?
Columns at the western end can be viewed from Waldronville and Blackhead Beaches. Formations on the seaward side are hazardous and hard to reach. Do not enter quarry land.
Is there a school or shopping centre in Blackhead?
No school or shopping centre has been verified in the suburb. Everyday shops and schools are in neighbouring southern Dunedin settlements, including Green Island.
Is Blackhead Beach a safe swimming beach?
It is a local surf beach under the headland, not a patrolled swimming beach. This coast is exposed, and conditions change quickly. It is not a place to treat as a family swim spot without local knowledge.
Which community board covers Blackhead?
That boundary was not confirmed from a named council list for this suburb. Use the Dunedin City Council election map and enter a street address to check the community board and ward.
