The THS owns a number of trams formerly operated in Christchurch, Dunedin, and Invercargill. It also owns a number of buses and trolley buses from Auckland, New Plymouth, Wellington, Christchurch and Dunedin along with an AEC Regent III double-decker bus, from London Transport, which was brought to New Zealand in 1974 to support the British Commonwealth Games team, and was purchased following the end of the games with the help of a generous donation from Farmers Trading Company. The society also leases Brisbane tram No. 236 from the Wellington Tramway Museum, and has done so since 1975.
