"It's not usually until Waitangi Day that we reach 100,000 visitors, and the activity hasn't only been at the weekends, it's been weekdays as well, including this week with its hot temperatures."
In September 2020, when level 2 Covid-19 restrictions were in place, the council deliberated on whether to open the venue or not given the uncertainty of Covid-19.
Ultimately, the council decided to go ahead with preparing to open in November 2020.
"It wasn't that many months ago that councillors were wondering if we could open the facility with the uncertainty around Covid-19," mayor Sandra Hazlehurst said.
"We chose to go ahead with opening it as we didn't want to lose the facility for our community and visitors and here, we are on track to having one of the busiest seasons ever.
"This is testament to the ongoing popularity of Splash Planet for those who live in Hawke's Bay as well as New Zealanders heeding the call to get out and explore the country."
