Onerahi is Whangarei’s only seaside suburb, a peninsula extending into Whangārei Harbour roughly 9 km south-east of the city centre. The suburb is connected to the mainland by the Onerahi Causeway and is largely surrounded by harbour waters, giving it a distinct coastal character. Whangarei Airport occupies the flat southern end of the peninsula, while a lower coastal road follows the foreshore. Across the harbour lies Motu Matakohe, also known as Limestone Island, the focus of a long-running ecological restoration project.

About Onerahi
Onerahi occupies a peninsula in Whangārei Harbour, a sheltered tidal harbour that opens south to the Pacific Ocean at Bream Bay. The suburb’s position means most residents enjoy direct harbour views, with the lower coastal road tracing the foreshore past beaches, boat ramps and reserves. The Onerahi Causeway provides the primary road link to central Whangarei.
The suburb features two main road circuits. An upper road follows the perimeter of Whangarei Airport, while the lower road runs along the harbour edge. This layout highlights the peninsula’s dual character as both an aviation hub and a residential coastal area.
Whangarei Airport sits entirely within Onerahi and serves as the main air gateway for the region. The airport site was developed using fill material from a former Māori pā located just to the north of the current runway area.
Motu Matakohe — Limestone Island
Motu Matakohe, known in English as Limestone Island, lies in Whangārei Harbour directly opposite the Onerahi peninsula. The 36-hectare island has undergone intensive ecological restoration since 1989, including pest eradication and native replanting to recreate a coastal broadleaf forest ecosystem. It was gazetted as a scenic reserve in 1999 and is now managed as a conservation refuge for native species.
The island is visible from the Onerahi foreshore and can be reached by kayak or boat. A floating dock improves access for visitors. Community groups continue active restoration work, and visits by arrangement are possible for those interested in the conservation efforts.
