Up until 150 years ago, each New Zealand region had its own, different time zone.

It wasn’t until the arrival of the telegraph and the steam train network that the need arose for accurate regional and national timekeeping.

In 1866, the first cable across Cook Strait was laid and regions between Napier and Bluff became connected by telegraph. Variations in operating hours at the relaying and receiving offices along the line initially hinder the smooth transmission of messages. So, in 1868 the Telegraph Department proclaimed that all offices had to adopt Wellington time.

This move lead to a parliamentary decree establishing a single time for the whole country – the first implementation of standard time in the world, which came into effect on November 2, 1868.

Today, the Measurement Standards Laboratory (MSL) at Callaghan Innovation(external link) is responsible for maintaining Official New Zealand Time. Read more about the unit of time, the Second here.

To commemorate the 150th anniversary, MSL is partnering with the Ministry for Culture and Heritage(external link) and the National Library(external link)  to deliver a free public event at the National Library in Wellington on Thursday 1November 2018, 5.45 – 7.30pm.

Join historian Gerard Morris as he takes us through the history of the adoption of New Zealand Standard Time. Also hear from Dr Bruce Warrington, Chief Metrologist and CEO of the National Measurement Institute, Australia, who will detail the science behind standard time and the technological innovations such as GPS it enables.

We invite anyone with an interest in time, its history, and significance in todays' society and the future, to attend this event.
