The history of Tiritiri Matangi

Lighthouse construction

Construction of the lighthouse was very difficult and cost £5,747. It took 4 months to dig down through 3 metres of thick, boggy, clay-like mud to reach ground that was hard enough to build on.

Building materials for the lighthouse were shipped to the island and then carted in sledges by bullocks over the slippery banks to reach the construction site. Despite the challenges of construction, the original tower is still standing. The light itself, however, has undergone many changes.

The light was first lit on 1 January 1865.
