In 1999, Reid won his first New Zealand Championship in Junior Stock which was preceded by wins in the Pro series.

[1] Reid drove for Graham Watson's Ralt Australia team in the 2003 Australian Drivers' Championship.

Reid finished the season with pole position and wins in both races in Round 6 at Eastern Creek.

Reid made his V8 Supercars debut in the 2003 Bathurst 1000 with Alan Gurr for Robert Smith Racing.

In the fourth round of the A1GP in Malaysia in Sepang International Circuit, Reid and Hülkenberg collided in the sprint race once again.

After doubling Team New Zealand's points in Malaysia, Reid was selected to drive in the fifth round in Indonesia.

[4] Four days later, he made his debut for Integra Motorsports in the 2008 Firestone Freedom 100 on 23 May at the Indianapolis Motor Speedway.

In wet conditions amidst many Safety Car periods, Reid led most of the race, which was run to time rather than laps due to the delays.

This effectively gave Reid the race win, but, with his radio having failed earlier, he was unclear on the situation and pitted at the end of the lap.

He returned one round later at Infineon Raceway driving a fourth car for Sam Schmidt Motorsports.

In 2010, Reid returned to the V8 Supercars series, testing with four other drivers for Kelly Racing in a session designed to evaluate potential co-drivers for the endurance rounds.

[7] This was followed up by drives in practice sessions reserved for rookies and co-drivers at the Ipswich[8] and Winton[9] rounds, before another test for the team in June.
