McRae sets pace with Wigram circuit of 107 mph
In an early practice run before the 1971 Lady Wigram Trophy, Graham McRae lapped the 2.3-mile Wigram circuit at 107.11 mph in his Chevrolet-powered McLaren M10B. Matich and Allen were soon lapping about 1.5 seconds slower, while Chris Amon's Lotus Boss Ford dropped a valve, leading STP to move him into the March 701.

Facts
- On 15 January 1971 Graham McRae lapped the 2.3-mile Wigram circuit at 107.11 mph (1min 17.3sec) in practice, 1.1 seconds slower than his record of the previous year.
- The Wigram circuit for the 1971 meeting was ready by 10.30am after the Motor Racing Club began setting it up at the airfield at 5pm the previous day, with straw bales for protection.
- STP had no replacement engine in Christchurch for Chris Amon's Lotus, so parts were sought by phone from the North Island for a major rebuild.
- Amon's March 701 Cosworth Ford 2.5-litre had been third in the first Tasman round at Levin a fortnight earlier.
