Westpac Trust Stadium

A world class sporting facility

Affectionately known as the ‘Cake Tin’ for its silver coliseum-like shape, Wellington’s Westpac Stadium was built in 1999 to replace rugby’s Athletic Park. Since then it has hosted many major sporting events and was second only to Auckland’s Eden Park for top fixtures in the 2011 Rugby World Cup. 

The first bowl stadium ever built in New Zealand, Westpac Stadium boasts a 34,125sq.m. footprint with an oval accommodating a 133m-long, 70m-wide football field and seating for 34,500 people. Stadium features include 69 corporate boxes, a Sports Hall of Fame, a sports medicine facility, conference rooms, a gallery 13m wide that extends 650m around the arena, sports betting areas, and café-bar and function rooms.

Of note is the 360 degree, 26m-high roof that partially covers the stadium and offers protection to 24,000 spectators in bleacher seating. Lighting for night matches is supplied by four 35m-high lighting towers each equipped with an 88m2 bank of 70 lights.

We were engaged on preferred contractor basis to provide buildability advice during the design phase, which led to the use of a number of innovative construction techniques including stone column ground stabilisation, lightweight concrete and fabrication of pre-cast concrete bleachers. Following the pre-construction phase, the designers were novated to us.
