Gibbons & Harris were manufacturers of narrow gauge geared steam locomotives between 1905 and 1912 in Auckland, New Zealand.

History

The steam engines of these locomotives were based on the design of those used for winches of ships, as known to Gibbons & Harris from conducting a lot of ship repair work. The boilers were purchased from other engineering companies manufactured. The locomotive had an average life expectance of 25 years.
