The peninsula end to end
Eleven kilometres of houses
The peninsula runs 11 km into the Hauraki Gulf and had 13,977 dwellings in 2023: 3,975 at Stanmore Bay, 3,525 at Red Beach, 2,298 at Manly and 2,190 at Gulf Harbour among them.
West first
Baches went up at Red Beach and Manly in the 1920s, suburban sections in the 1950s, and the western end urbanised rapidly from 1964 to 1975.
East later
The eastern peninsula developed from the late 1980s, so Gulf Harbour and Army Bay homes are mostly younger.
Cliffs on the move
Slips closed the Army Bay stairs and the Arkles Bay walkway in January 2026. Auckland Council's chief engineer says the landslides are mostly natural erosion, and three houses have been removed from the cliff edge at Fisherman's Cove.
Hot water on pilot wire
Vector says North Auckland hot water may be on pilot wire, which is repaired after the power lines come back.
What each end tends to need
Red Beach, Stanmore Bay, Manly. Houses from the 1960s and 1970s, some built on old baches. Expect older boards and fewer power points than a modern family needs. A switchboard upgrade and a few new circuits are the usual first jobs.
Gulf Harbour, Army Bay, Tindalls. Mostly newer homes with modern boards. The work is EV chargers, heat pump circuits and outdoor lighting.
Cliff-top properties. If ground movement has shifted a garage, a fence or a path, check that any outdoor cable or a supply to a sleepout hasn't been pulled or crushed. Leave it off and get a licensed electrician to test it.
If we lived on the peninsula
We'd ask an electrician to look at outdoor wiring every few years if the section is on a slope or near the cliff edge. Ground that moves slowly can stretch a buried cable without anyone noticing, and a test catches it before the RCD does.
