A shopping centre owner is worried that the $40 million extension to Manukau's courts will pinch public carparking.
Court officials advise visitors to use the pay-and-display parking on streets near the courthouse and those arriving after 9am often have trouble finding one.
The lack of public parking has resulted in people using free spaces in the nearby Westfield shopping centre, said a submission from Westfield NZ to Auckland Council planning commissioners hearing a case for enlarging the court site's boundaries.
Court growth would raise demand for carparks and put more pressure on the centre, said Westfield development executive Allan Lockie.
The centre had to lease its 2001 spaces from the council "at a considerable cost".
