The New Zealand Road Race Championship Round 1 and New Zealand Motorcycle Grand Prix.
The New Zealand Grand Prix held on the Cust road circuit between the years 1936 – 1963 were a unique annual event in New Zealand during that time. They were run by the Canterbury Auto Cycle Club Inc. under the rules and regulations of the N.Z.A.C.U. The races were held on Easter Monday each year with a practice on the Saturday. There were no races during the war years 1941-1946, as many men were overseas. There were 22 years of races. When the Canterbury Car Club opened a sealed track at Ruapuna Park in 1963 the NZ Grand Prix was transferred to a new venue, thus ending the Cust era. The NZGP has never been run anywhere else other than Canterbury and 2013 will see the 71st running of the event.
