Six of Nicole's colleagues jumped on board and the event raised $290 for the Cancer Society.
"The kids loved it and the staff were really into it, too."
Flaxmere councillor Henare O'Keefe was also set for a dunking next week, after his children challenged him as part of the campaign.
Mr O'Keefe said his version of the challenge would take place in the Hastings CBD "rain, hail or snow," on Monday at 1.30pm.
Mr O'Keefe, along with Hastings Mayor Lawrence Yule and Tukituki Labour candidate Anna Lorck, would get three buckets of iced water poured over them, while they soaked their feet.
"It's to show people that we [the council] are more than just bricks and mortar."
Other unnamed guests were billed to take part and Mr O'Keefe had extended the challenge to the Hawke's Bay Regional Council and Napier City Council.
The proceeds would be donated to Cranford Hospice.
