Railway preservation in New Zealand is the preservation of historically significant facets of New Zealand's rail transport history. The earliest recorded preservation attempt took place in 1925, although the movement itself did not start properly until 1960.

History

Early initiatives

Early preservation efforts in New Zealand were restricted to static public display of locomotives, and it is believed the first was Double Fairlie E class locomotive E 175 Josephine outside the Dunedin Railway Station in 1925. After this, the preservation movement entered a hiatus until the founding of the New Zealand Railway and Locomotive Society in 1944, which established branches throughout the country. The first act of active railway preservation was started by the NZR&LS Otago Branch when they purchased a small 9-tonne Fowler 0-4-0T tank locomotive built in 1921 and formerly used by the Public Works Department as their N<sup>O</sup> 540, from the Otago Harbour Board for use on the fledgeling Ocean Beach Railway, established in 1963.

Similar works were soon started in Christchurch by the NZR&LS Canterbury Branch at their new Ferrymead Railway in Christchurch, the NZR&LS Auckland Branch at their Glenbrook Vintage Railway and the NZR&LS Wellington Branch at their Silver Stream Railway. A railway museum was established at Te Awamutu by the NZR&LS Waikato Branch. However, this period also saw the breakaway of the NZR&LS Auckland and Canterbury Branches to become the Railway Enthusiasts Society and the Canterbury Railway Society respectively, although they retained an affiliation with the NZR&LS.

1960 to 1985

During the period from 1960 to 1979, the rail preservation scene began to increase as more railway museums and groups were established, helped in part by the closure of rural branch lines by New Zealand Railways. In this category, railway museum groups were set up by the Pleasant Point Museum and Railway at Pleasant Point and the Ashburton Railway and Preservation Society at Tinwald Domain near Ashburton in Canterbury. These groups at the time were attempting to save part of the fabric of rural branch lines that had been operated by New Zealand Railways but were being closed down.

As the replacement of steam was accelerated during this period and was completed in 1971, The Rail Heritage trust pioneered the concept of "heritage rolling stock" which was leased to various preservation groups around New Zealand by Tranz Rail. Over 200 such items of rolling stock are now leased.
