But similar moves are not planned for the timber walkway next to the Whanganui River on Taupo Quay.
Greg Hoobin, Whanganui District Council building control team leader, told the Chronicle that in 2007 the council issued a code compliance certificate for the boardwalk. This did not require barriers, based on the limits of application of the building code.
"The application of the building code can, at times, be a subjective matter based on consenting practices of the day," Mr Hoobin said.
He said the boardwalk was constructed to the approved plans and was subsequently issued a compliance certificate.
"The difference between the Whanganui River boardwalk and the Mangonui project is that both the resource consent and building consent for the Mangonui project had stipulated a barrier which had not been constructed," he said.
