The ever-growing PVD settlement-on-wheels is in a tsunami evacuation zone. It has about 30 PVDs including housetrucks, old unregistered buses, old campervans, caravans, vans and cars that are home for about 50 people living on the site nightly.
Alcohol, drugs, mental health challenges and rubbish are among encampment issues.
The council-owned carpark - dubbed homeless heights by its locals - is on Whangārei's Okara Drive/Porowini Ave roundabout corner and is a crucial parking space for the multi-event stadium and cricket. Its PVD encampment is the biggest in Northland.
The growing number of PVDs highlights a wider district trend with people living permanently in old buses, house trucks, vans and cars.
"It's the off-season now and I've never seen as many vehicles here as there are now, even over the summer peak," Hart said.
Many of the PVDs are challenged by the district's growing housing affordability issue. A recent WDC housing monitoring report said there was a growing issue of affordability in the district aligned with a rapid property value increases. Rents had gone up. It had become more difficult to transition from renting to home ownership.
"Many of these people don't have other options," Lisa Cassidy-Nelson, Whangārei's One Double Five chief executive, said.
The situation was complex, solutions multiple, she added.
The about 200-car carpark provides parking for adjacent 25,000 capacity multi-event stadium and up to 5000 people at Northland Cricket's Cobham Oval games.
Northland's first major post-Covid lockdown rugby game will be held at the stadium in eight weeks.
Cameron Bell, Northland Rugby Union chief executive, said about 12,000 people were expected for the Mitre-10 Cup provincial rugby series game between Northland and Manawatu on September 13.
Bell said it would be concerning if the parking space wasn't available. It provided crucial close stadium access for older people, the disabled and young families.
"I would be distressed if they turned up and couldn't get access to the games."
Hart said, working with the council, the PVD "settlement on wheels" moved out of the carpark for the day for events at the stadium and cricket pavilion.
Stephen Cunis, Northland Cricket Association general manager, said the Cobham Oval carpark would be used for games such as internationals including the Black Caps, that attracted larger crowds.
Reiner Mussle, WDC manager health and bylaws, said the council viewed PVDs as outside the intent of the bylaw and the Freedom Camping Act.
"Vehicle dwellers and homelessness are broader social issues that do not fall under the bylaw. Over the years, council and our contractors have worked through issues around permanent vehicle dwellers and homeless people sleeping in cars sympathetically and pragmatically," he said.
"However, it is becoming more and more difficult to balance the wishes and needs of homeless people and vehicle dwellers against complaints from the general public, as well as from freedom campers, who don't understand the differences between genuine freedom camping and homeless people/permanent vehicle dwellers."
Cassidy-Nelson said PVDs could not be compared with freedom campers.
"One is a community that has choice, the other community is disadvantaged," Cassidy-Nelson said.
Mussle said he would be working with PVDs and other areas of council to develop practical strategies on how to better manage permanent vehicle dwellers and homeless people sleeping in cars - before the next freedom camping season.
Options could include finding sites where they were able to "park" for a longer time, a permit system in place to manage this.
"However, such sites should be suitably separated from freedom camping sites, identified under the bylaw, to avoid rule confusion and allegations of double standards," he said.
Hart said parks that worked for Whangārei's district's permanent vehicle dwellers should be created. These could provide user-pays facilities – $2 for a shower, power, hot soapy water for dishes, internet or a barbecue and $5 for a clothes dryer.
