Stage two of the rollout involves a "scan car" hitting the streets.
The car is fitted with a camera which scans car registration plates.
Weston said the car would be on the road in the next couple of weeks and would initially be checking for out-of-date registrations and warrants of fitness.
As the new parking meters are rolled out, from mid-November, the car will also scan for cars which haven't paid for parking or have gone over the time they've paid for.
The car then communicates directly with the parking wardens.
The first group of 10 parking terminals will be installed from next month with the remainder to be installed by the end of January.
Williams said the machines were "very good quality" and included several payment options.
The new-look terminals are solar powered, with a 17.7c mdigital screen used to input your car registration plate, instead of a standard pay and display.
After public consultation found many road users wanted to still use coins half of the terminals will still be able to take coins.
All of the terminals will be able to accept debit and credit cards with chips or paywave.
"What we're looking for is these machines to replace the approximately 800 meters currently out in the city, there'll be about 76 of these new machines out on the street," Williams said.
"The key difference is to move away from a standard pay and display, to a pay by plate system instead."
There will be one terminal for every 20 parks and where a machine does not take coins, there will be one located across the road that does, he said.
Additional functions will be introduced after the system is fully implemented and running well.
This includes the ability to pay using a parking app, the ability to promote information such as notices and events on the digital screen and the option to use multiple languages such as te reo Māori.
Parking policy and fee setting remain with the council and the changes will take effect as the scheme rolls out, including retaining an hour of free parking in the inner city where there is already free parking.
