AT will be meet representatives of nearby businesses today to work on a plan for other parking options in the vicinity. This may include removing or altering other parking time restrictions in the area.
Auckland Transport initially banned SUVs, vans, utes and commercial vehicles - any vehicles that weighed more than 2000kg - from the upper deck.
After many overweight vehicles continued to drive on to the structure, security guards were last week hired to hand notices explaining the ban to drivers of potentially-overweight vehicles. They were directed to the lower level.
The upper deck of the two-level carpark is a deteriorating platform that has suffered from water ingress.
Numerous repairs have been made to the platform, but problems remain. The carpark was built in 1982.
Auckland Transport had been trying to extend the platform's safe, usable life by limiting the weight it carries.
