Museum about the early settlers:

An interesting museum the extra showing a strong box for the state coach and a little of the wondrous looking railway station next door.

From the Internet:
The story begins with a journey through the eyes of the first arrivals, Kai Tahu Māori, through the growth of the city, including the seedier side of early Dunedin, the rowdy pubs, and the ladies of the night, and culminating in Future City which focuses on the challenges facing Dunedin today.

In 1861 Dunedin was a village of some 2000 people. Civic leaders knew gold was to be found in Otago but they feared the opening up of goldfields would prompt hordes of unruly and immoral miners to descend upon them and destroy the ideal society they were trying so hard to create.

However, the gold rush began and transport was need for thousands of miners and for the gold to be transported initially in leather bags later in a strong box.
