The signs in the Valley Rd car park belong to AmalgAmated Carpark Services, which is owned by Supercity Towing in Eden Terrace.

Carmina Jacobson shared on Facebook her costly takeaway experience.
"I was parked for two minutes next to the Burger Fuel store, went in to pick up my order and came out to see my car being clamped," Ms Jacobson told Te Waha Nui.
"The only way to have it unclamped was by paying $250 to the man."
Glen Yare was picking up a Burger Fuel order for his family, accompanied by a friend, when he was targeted.
According to Mr Yare, there were no other cars, and his vehicle was not taking up any spaces.
"We were parked for three minutes and returned to see a guy with an EFTPOS machine demanding $150."
Mr Yare said the man "was unprofessional, laughing and saying 'we've got you'".
"He was parked in an unmarked car and refused to show me ID, he just pointed to a company name on his T-shirt."
Initially Mr Yare refused to pay up but the parking enforcer said he would tow the car and it would cost $270.
"Next time this happens I will dispute the charge," said Mr Yare.
"$150 for three minutes seems unjust, I felt like I was robbed."
Automobile Association (AA) senior policy analyst Mark Stockdale said there were no laws governing private car parking and the use of clamping.
"From the AA perspective it is an anomaly that the private parking sector are not subject to regulations when the Auckland Council sector is," said Mr Stockdale.
The price of penalties set by private parking enforcement businesses was different to those set by Auckland Council.
"If all parking enforcement companies were signatories to a voluntary code of practice it would be much fairer," said Mr Stockdale.
"The Code of Practice for Parking Enforcement on Public Land was developed with the private parking sector and sets out guidelines, including minimum signage and recommended enforcement practices."
