Rangitoto Lighthouse, Concrete lighthouse in McKenzie Bay, New Zealand.

Rangitoto Lighthouse is a cylindrical masonry tower 20 metres tall, painted white with five red bands, standing on a small islet just west of Rangitoto Island in Auckland's Hauraki Gulf. It has a gallery but no lantern, and its focal plane is 21 metres. It flashes a 1.5-second red light every 12 seconds, visible for 7 nautical miles.

The lighthouse was built in 1882 and originally produced red flashes every 12 seconds to guide ships through the waters. Over time, the original balcony and lantern were replaced with modern systems that improved navigation in the region.

The beacon stands on a small islet just west of Rangitoto Island, so 4x4 tours of the island reserve often pass close to it. Its red and white paint and 12-second red flash make it a landmark for boat traffic in the Hauraki Gulf.

The lighthouse stands on a small islet just west of Rangitoto Island and can be reached only by boat; the site and the tower are closed. Rangitoto Island itself is a nature reserve reached by ferry from central Auckland, and 4x4 tours of the island often pass near the beacon.

The light is not classed as a lighthouse by the New Zealand Maritime Safety Authority, yet it still flashes red every 12 seconds. Its 1.5-second flash reaches 7 nautical miles, and the whole beacon runs on solar power, monitored from a Maritime New Zealand control room in Wellington.
