The Tokomaru Steam Engine Museum is a private collection of machinery founded by Colin and Esma Stevenson. The museum opened to the public in 1970 after constant requests from steam enthusiasts. Thousands of visitors from all over the world have enjoyed reminiscing amongst the relics of New Zealand's industrial and agricultural heritage.

The museum has recently changed ownership, and is now operated by Damian Groves and Roxanne Eastham, a couple with a young family who are dedicated to preserving Colin and Esma's legacy.
