The proposal to turn about 90 of the garden's 140 parks into 240-minute time-restricted parks is contained in a report by Queenstown Lakes District Council transport manager Denis Mander.
Alongside a handful of other proposed parking changes, the proposal will come before the district council infrastructure services committee tomorrow.
It initially surfaced in the Queenstown Gardens Reserve Management Plan adopted in April, envisaging the southern car park and part of the northern car park as restricted.
Mr Mander said car-park use had been surveyed, and it was determined 50 parks were sufficient to meet the needs of town workers, about 30 to 40 of whom used them each day.
"If we put in more restrictions, it would relocate people into the neighbouring streets, but we are trying to keep a balance to ensure that in the future it also remains accessible to visitors," he said.
"We know that parking demand will grow, so it sets that cap of about 50 parks."
The four-hour time restrictions would be imposed from Monday to Friday between 8am and 6pm. Those at weekday tennis and bowling club events would be able to stay longer.
Parking restrictions were also proposed for two Frankton streets close to the airport popular with "people seeking free parking while out of Queenstown".
Both Douglas St and Humphrey St provide access to the Lakes District Hospital's accident and emergency department, with the latter's parking also on a bus route and regularly used by fire engines.
The report recommended banning parking on both sides of Humphrey St, and installing and monitoring 48-hour parking restrictions on Douglas St.
Hospital restrictions against overnight parking on its Douglas St land earlier this year resulted in "pushing the parking south along Douglas St and into Humphrey St, with increasing complaints from residents and road users resulting".
Also proposed in the report is the creation of two mobility parks, one next to the Queenstown Memorial Hall and another in the Queenstown Gardens northern car park, close to the entrance.
If the committee backs the recommendations, they will come before the next full council meeting on December 16.
