The story

This impressive, elevated place overlooking Whakaraupō Lyttelton Harbour is known to mana whenua, Te Hapū o Ngāti Wheke, as Urumau. Directly underneath here, around 150 metres down, was originally a cave by this name. Now it's the name also given to the ridge above this site, Urumau Reserve.

The Lyttelton Timeball, built in 1876, was Aotearoa New Zealand’s third and final timeball station. Until 1934, a ball dropped from the mast on the stone tower each day at one o’clock. This signal let ship’s masters in Whakaraupō Lyttelton Harbour check the accuracy of their chronometers. A precise ship’s clock was essential in measuring longitude for maritime navigation.

Generations of timeball keepers and their families lived onsite and cared for the timeball’s clever mechanised winding apparatus, which lifted the ball up, then allowed it to drop. The timeball was phased out in 1934 as radio-telephone technology advanced.

During the 1960s the Lyttelton Maritime Association and community volunteers restored the station and gifted it to New Zealand Historic Places Trust (now Heritage New Zealand Pouhere Taonga). From 1978, the timeball resumed its daily practice.

Several decades later, the Ōtautahi Christchurch earthquakes of 2010-2011 badly damaged the timeball station and the castle-like structure was carefully deconstructed. In 2018, the rebuilt 10.4m tower, complete with restored zinc ball and an all-new automated mechanism, rose again over the Lyttelton skyline. A pou created by Ngāti Wheke kaiwhakairo Caine Tauwhare now stands alongside the reinstated Timeball tower, symbolising the long history of Māori celestial maritime navigation in Aotearoa.

The site is cared for and operated by Heritage New Zealand Pouhere Taonga.
