The Schofield tank, named after its designer, was a New Zealand tank design of the Second World War. Developed in 1940 when it seemed that the Pacific War might reach New Zealand and with little likelihood of weapons coming from Britain, it did not enter service. It was designed to run on either tracks or wheels.

In around June 1940 Ernest James Schofield, a motor vehicle dealer for General Motors in Wellington, approached his MP William Theophilus Anderton with an idea for a fighting vehicle that could run on tracks or wheels.^[1] He had at this stage constructed a basic model from Meccano showing the basic principle of operation.^[2]

Schofield's tank was based on the chassis of a Chevrolet 6 long hundredweight (300 kg)^[3] truck using the suspension from a Universal Carrier. Wheels normally carried on the hull could be bolted on so that it could use these rather than the tracks. As initially designed it had a crew of three: machine gunner and driver at the front and a second machine gun in a turret at the rear.

The initial design performed badly in trials but the Government sought an improved version. Designed by another member of the original team, the improved model used a better transmission and the turret now contained a QF 2 pounder gun with a co-axial Besa machine gun. By the time it was complete, in 1942, New Zealand had received tanks from the UK and US.

The armour plating was provided by the New Zealand Railways. The four wheels shared drive and idler sprockets with the track, and the move from wheels to track, and vice versa, could be made from within the hull.

In 1943 the improved design prototype was shipped to Britain, where it was evaluated by the Department of Tank Design. Although not completely critical, the project was advised to be stopped. The tank was stored for a while and scrapped after the war.^[4]
