The 1950 New Zealand Grand Prix was a motor race held at the Ohakea Circuit on 18 March 1950. It was the first New Zealand Grand Prix to be held, was held to Formula Libre rules and was run by the Manuwatu Car Club.
The event was won by John McMillan driving a Jackson Special who was followed in close pursuit by Hec Green. The field consisted largely of local drivers with the only exception being Australian driver Garry Coglan who secured the pole position. Following this event, the New Zealand Grand Prix would lie dormant for three years before returning in 1954.
