The New Zealand tank.
There are any number of jokes about how well equipped our military are or have been.
But once upon a time, we designed our own tank.
Well, what we really designed was uniquely Kiwi. An armoured tractor.
In the Second World War we needed military hardware. In particular we needed armoured vehicles. So in the usual Kiwi way, we adapted.
Minister for Works at the time was Bob Semple and he and Thomas Beck, a Christchurch engineer, set about designing and creating one.
There were no blueprints or formal plans. What they had was a postcard from America. One that showed a tractor-tank conversion.
It was decided that a 'tractor-tank' would be an adequate design; if the need for defence arose, a large tank superstructure could be bolted upon a tractor base within a few hours, allowing for quick transformation and deployment of the tanks.
It also needed tracks rather than wheels so the first prototype was built on a Caterpillar D8 crawler tractor. We didn’t have heavy artillery of course, so instead it was equipped with six Bren light machine guns.
When finished, the ‘tank’ was 12ft tall - making it unwieldy. And it’s armour plating - well we used corrugated iron. That’s right, a good old Kiwi tank made out of corrugated iron.
The first was built at a Temuka workshop in June 1940 for the grand cost of £5,902 by the Public Works Department who could make 81.
The intention was to disperse the hulls at locations ready in case of a Japanese invasion at which point they would be mounted on tractors for use.
But the tanks were too heavy, with not enough armour, and slow, having to stop to change gears.
They never saw combat and were eventually quietly disposed of.
Robert Semple was born in New South Wales on October 21, 1873, to John and Mary and began his working life as a gold miner at the age of nine.
After being blacklisted during a strike he moved to the West Coast and became president of a miner’s union.
He was jailed in 1913 for supporting the general strike and again in 1916 after fighting conscription for overseas service during World War I. Semple served as the President of the Labour Party from 1926 to 1928.
Semple was also a Wellington City Councillor then elected to the Wellington South Parliamentary seat.
He later won the seat of Wellington East which was later renamed Miramar.
During his time in Parliament he was the Minister of Public Works and Minister of Railways.
He did not seek re-election in 1954 and died on January 31,1955 and was cremated at Karori Cemetery.
