Ms Worth said her daughter Keitana had been in a pushchair, though she had picked her up to comfort her when it began to rain.
"I was so eager to do that walk as I'd never been there." Ms Worth said she would like to see Whangarei District Council investigate an anti-slip solution for the walkway.
WDC senior landscape architect Bruno Gilmour said an immediate solution to the slipperiness was being investigated after complaints from Ms Worth and other walkers. The section of boardwalk nearest the Town Basin playground was already water blasted regularly but Mr Gilmour said all sections including the triangular "bump outs" would now be water blasted to remove any slippery residue.
"In the long term we want to address it in a more fundamental way ... Chicken mesh works OK in the short term but creates bigger problems in the long term. We need to do something that makes it more practical to maintain as well as being attractive."
Mr Gilmour said he had spoken to Ms Worth to and ensure she was unharmed.
"We're aware of it and are doing everything we can to remedy it," he said.
Ms Worth said she thought the solution "sounded good".
"The walk was beautiful and looks great. So I will definitely be returning at some stage to finish our walk."
