Contractors are back in action for the final push on the Anzac Pde slip area after work stalled several weeks ago.
At the time, Horizons Regional Council said it was waiting for information from the New Zealand Transport Agency (NZTA) to enable the resource consent for the work to be completed, while NZTA said it was waiting for documentation from Horizons.
Horizons' strategy and regulation group manager Dr Nic Peet said a consent has now been granted as NZTA provided the required information.
With the paperwork now complete, NZTA system manager Mark Owen said he was confident the work would be wrapped up quickly, with the repairs 80 per cent complete and expected to be finished by late October.
"The work we are doing now means a much more resilient riverbank along Anzac Pde and that the riverbank will be better able to withstand future flooding," Owen said.
