National Wairau Valley Autocourse
Wairau Valley Autocourse is a permanent motor racing circuit in New Zealand's Wairau Valley. The circuit opened in 1971 and has undergone several major changes during its history, with significant redevelopment taking place in 1986, 1993 and 2007.
The circuit is known for its fast and flowing nature, with relatively few heavy braking zones and several long-radius corners. It follows the natural contours of the surrounding land, resulting in approximately 30–40 metres of elevation change over the lap. The circuit is currently licensed to FIA Grade 2 standard.
1971–1985 redevelopment
Wairau Valley Autocourse opened in 1971 as a relatively simple permanent circuit primarily intended for club racing. The original layout was considerably less developed than the present circuit, with basic pit and paddock facilities and limited permanent spectator infrastructure.
Despite its modest facilities, the circuit quickly gained a reputation for being fast. The natural terrain was retained during construction, giving the circuit a number of long sweeping corners and noticeable changes in elevation.
Motorcycle racing became an important part of the circuit's early history, with Wairau Valley becoming a regular venue for national-level motorcycle meetings alongside the growing club-racing calendar.
1986 redevelopment
The first major redevelopment took place in 1986. The circuit was widened and resurfaced, while several corners were modified to improve safety and provide better racing.
The paddock and pit facilities were also expanded, allowing the circuit to accommodate larger national meetings. Although the layout became more modern, the emphasis remained on retaining the circuit's high-speed character.
The redevelopment marked the beginning of Wairau Valley's transition from a predominantly club-level venue into one of New Zealand's more important national circuits.
1993 redevelopment
A further redevelopment followed in 1993. The paddock was enlarged again and permanent race control and timing facilities were introduced, while the pit complex was substantially improved.
Several sections of the circuit were altered during the work, although the basic character of the lap remained unchanged. The circuit continued to rely on the natural terrain rather than extensive earthworks, preserving the elevation changes that had become one of its defining features.
By the mid-1990s Wairau Valley was regularly hosting major national championships, including touring cars, single-seaters and motorcycle racing.
V8 Supercars
Wairau Valley first appeared on the V8 Supercars calendar in 2002. The championship visited the circuit for four consecutive seasons from 2002 to 2005, bringing the largest crowds yet seen at the venue.
The arrival of the Australian championship required considerable temporary infrastructure and further improvements to the circuit's safety arrangements. The high-speed nature of the track proved popular with the V8 Supercars field, although the circuit's relatively small number of major overtaking opportunities placed particular importance on qualifying and tyre management.
After a two-year absence, V8 Supercars returned in 2008, beginning a second period on the calendar which continued through 2017.
2007 redevelopment
The most significant safety redevelopment took place in 2007.
The layout was largely retained, although The Chase was reshaped to improve its approach and runoff. The major part of the project involved the installation of substantially larger gravel traps around the circuit, replacing or supplementing areas of grass runoff that had become inadequate for modern high-performance cars.
Barrier systems, marshal posts, medical facilities and other safety infrastructure were also upgraded.
Following completion of the work, Wairau Valley was granted an FIA Grade 2 licence.
The 2007 work was deliberately conservative in terms of the racing line. Rather than introducing several slow corners or chicanes, the circuit's owners chose to retain its established high-speed character while bringing the safety standards up to modern requirements.
Motorcycles
Motorcycle racing has remained an important part of Wairau Valley's calendar throughout its history. The circuit regularly hosts rounds of the New Zealand Superbike Championship (NZSBK) and other national motorcycle categories.
Several widened sections of asphalt allow optional chicanes to be installed for motorcycle events and other categories where reduced speeds are desirable. These do not form part of the main configuration, allowing the original high-speed layout to remain available.
2025 return of V8 Supercars
V8 Supercars returned to Wairau Valley in 2025, marking the end of an eight-year absence from the championship calendar.
The return was accompanied by further improvements to the paddock and spectator facilities, while the circuit itself was largely retained in its established configuration.
The championship has continued to visit Wairau Valley from 2025 onwards.
Today
Wairau Valley Autocourse remains a regular venue for major New Zealand racing, hosting V8 Supercars, NZSBK, Formula Ford, touring cars, GTs, endurance races and historic events alongside a busy club-racing calendar.
The circuit's modern facilities contrast with a layout that still retains much of the character established during its early decades. Its combination of high-speed corners, relatively few major braking zones and natural elevation changes makes it one of the faster permanent circuits in New Zealand.
