The latest update to the state government's Park'nPay app will see drivers benefit from partnerships with Australia's largest EV charging network Chargefox and parking marketplace Parkhound.

The Park'nPay app will connect drivers with more than 18,000 Parkhound hosts, who are renting out their private driveways and parking spaces. EV drivers can now also locate 130 charging stations with almost 240 plugs across NSW via the app's map.

Digital and Customer Service Minister Victor Dominello said the app provided a single seamless platform for drivers looking to plan their trips.

"Alongside the real-time parking availability, money saving pay-as-you-go technology and remote topping-up facility, having all this information accessible in the one place is a big win for the drivers of NSW," Mr Dominello said.

"This is a smart solution for a smart state."

Transport and Roads Minister Rob Stokes said the Parkhound feature can be used by drivers to find the perfect spot when street parking isn't available.

"...While giving hosts the chance to make some extra cash when their car spots would otherwise sit empty," Mr Stokes said

"The NSW Government's $490 million Electric Vehicle Strategy is leading the nation in the uptake of electric vehicles, and the partnership with Chargefox is a great way for EV drivers to find a parking spot and charge their vehicles at the same time."

Parkhound chief executive Mike Rosenbaum said there are 100,000's of underutilised driveways and car spaces that sit idle right across the state.

"Both commuters and local residents can now easily make use of these otherwise wasted spaces via the real-time data in the Park'nPay app," he said.

"This will significantly ease parking congestion and save drivers from circling the block."

Chargefox chief executive and co-founder Marty Andrews said: "The Collaboration with ParknPay means that motorists will have more visibility about EV charging infrastructure, which has been a barrier to EV uptake in the past. We look forward to adding more station locations to the app in the future as we work towards our goal of a 5000 plug EV charging network by 2025."

The Park'nPay app has a link which will direct users to Chargefox when it is time to pay.

More than 71,400 people have downloaded the Park'nPay app across 10 Local Government Areas - including Liverpool - with almost 94 per cent giving it a thumbs up.
