If you spend $10 or more at any Hastings CBD business on the same day as your Bumper Boat booking, you get free entry for one person.
Eligible Hastings CBD businesses can be found on the Hastings City Business Association's website.
Vaccine passes are compulsory for all participants 12 years and older - accompanying parents or guardians without a vaccine pass can escort children to the entrance of the activity only.
Hastings City Business Association general manager Emma Sey said it was putting on the event with Event Hire - the first time the bumper boats have come to the Bay.
"It will be quite interesting to see how it goes and how it's received, but we've got quite a lot of bookings already, which is promising."
She said the association wanted to do something similarly exciting to the ice rink they did in 2020 to bring more people into town over the summer.
The bumper boats are funded by Hastings City Business Association with further funding support from Hastings District Council.
