Swiggs said he was appalled potholes and puddles were permanent problems at the car park used by visitors, including elderly citizens and patients, to Christchurch Hospital.
"If people are willing and able to walk a little bit, the Lichfield Street car park is three blocks away from the hospital."
Swiggs said elderly residents and patients in wheelchairs were being blatantly ignored by the car park's owner.
"The reality is that the CDHB are paying a lease for it, so the owner of the land should be stepping up and having a fit-for-purpose car park," he said. "It's a disgrace."
Swiggs recommends visitors consider using the new council-owned Lichfield Street parking building or take public transport instead.
"I do wish the CDHB had delivered a solution a little bit quicker," Swiggs said. "They've still got the site of the old car park building that is just sitting there empty."
The car park, privately owned by Southern Demolition and Salvage Ltd director Alan Edge, is the temporary hospital parking site ahead of a designated hospital parking building expected in 2020.
