The NSW Government's Dine & Discover initiative will be extended by a month to give people more time to use all of their vouchers eating out or trying a new activity this winter, including in the upcoming school holidays.
The vouchers had been due to expire on June 30, but have now been extended to Saturday July 31.
The latest data shows more than 4.23 million people in NSW have downloaded the vouchers since they were launched in March spending a combined total of more than $357 million with registered businesses when adding in the additional spend on top of the voucher amount.
Local Nationals Member of the Legislative Council Ben Franklin said the stimulus had proved popular and played a valuable role supporting local businesses as well as reviving consumer confidence.
"This program is win-win for communities - it's provides individuals and families with hip pocket relief and helps local businesses with much needed stimulus," Mr Franklin said.
"People of all ages and walks of life are giving them a go and we don't want anyone to miss out. This extension will ensure everyone has a chance to use all four of their vouchers, which I'm sure will be particularly handy in the school holidays.
"There are hundreds of participating businesses across the Northern Rivers including cinemas, theatres, bowling, cafés and restaurants - plenty for the whole family to enjoy."
Dining out has been particularly popular, with patrons across the State spending on average $41 for every $25 voucher used.
Mr Franklin said the enthusiastic take up of the vouchers showed digital initiatives were the way of the future.
"It's not too late for businesses to register and customers are encouraged to sign up and spend their vouchers before they expire on July 31, 2021," Mr Franklin said.
"We're giving people more time to take full advantage of these vouchers, so make sure you sign up and use them before you lose them."
Every adult in NSW is eligible for four $25 vouchers worth $100 in total, to spend across the 14,000 participating businesses.
The vouchers are free and are not means tested.
Vouchers can be accessed via the Service NSW app; online at www.service.nsw.gov.au; in person at your local Service NSW centre or over the phone with Service NSW on 13 77 88.
