It wanted the rest to use public transport, walk, or cycle.
That was in line with an Environment Court consent order aimed at enhancing the commercial and economic development of an area which was constrained by limited access points.
Although Air New Zealand as a major employer at the edge of Wynyard Quarter had already achieved the desired ratio through educating its staff about travel alternatives, about 60 per cent of movements to and from the zone were still by car.
But Mr Rednall said that as the area was only 17 per cent of its way towards full development, ample opportunity remained to turn that around, and promising results had been achieved from new bus services.
Buses from central Auckland, which were free to holders of electronic Hop cards, brought about 400 workers to Wynyard Quarter each morning and up to 500 people walked to work across the relatively new Te Wero bridge.
Although only about 20 per cent of an ultimate working and residential population of 20,000 or so people are so far based in the precinct, the ASB Bank will provide a major boost next year when it opens a new head office for almost 2000 staff.
Other future travel options will also include a walking and cycling bridge across the motorway from St Marys Bay, and an extension of the Wynyard Quarter tramway to Britomart.
