Work has started to remove high-risk woody debris from the lower Waimatā River in Gisborne.
The work is being done over a 4km section between Waimata Cheese (161 Riverside Rd) and the William Pettie Bridge (linking Rutene Rd and Ormond Rd).
It will focus on debris that built up duringCyclone Gabrielle and subsequent severe weather events, Gisborne District Council said.
“This material can restrict river flow, trap more debris during floods and create hazards for river users and nearby infrastructure,” woody debris programme manager Rod Sheridan said.
“The lower section of the river was prioritised due to its high use by the community and proximity to residential areas and key infrastructure.
“That part of the Waimatā is well used by recreational groups and the wider community, so it’s important we reduce the risks while keeping the river usable.

“The work is targeted at material that poses the greatest risk. It’s not about removing everything but focusing on debris that could move during a flood or block the river.”
Work will be done in stages over the coming months. Crews will start in two sections – one near Marian Drive working towards William Pettie Bridge; the other near the cheese factory, working downstream towards Marian Drive.
“A range of methods will be used depending on the location and type of material, such as cutting and removing large logs, clearing smaller debris and removing underwater material where required,” Sheridan said.
Care has been taken to plan the work in a way that minimised environmental impacts.
“Vegetation that supports riverbank stability will be retained where possible and the work will be carried out in a way that reduces disturbance to the river.
“Residents and river users may notice contractors working along sections of the river, along with temporary noise from equipment and short-term restrictions in some areas.
He reminded people to take care around work areas.
