He says consultation with stakeholders is under way now to gather feedback on how the facility will be used and features needed.
"The design will make the new east stand more usable, more often, by more people because flexible use spaces are being built into the new stand."
For example, he says, amenities will be designed in a way that allows outer field users to access changing rooms without opening up the entire facility.
Yarrow Stadium will reopen in 2022 with the repaired West Stand, but the new stand will not be available until late 2024, with construction scheduled to begin towards the end of March 2022.
The council has budgeted $50m for the refurbishment of Yarrow Stadium, $20m of which is funded from the Covid-19 Response and Recovery Fund.
"We acknowledge that constraints in the building sector may put pressure on that budget, but it is our intention to stay within the $50m approved and agreed by ratepayers.
"The project has been designed to focus on the core components of the stands, field and lighting, with enhancements to surrounding areas to be considered once we have greater certainty on final costs."
The stand replaces the existing East Stand which was closed in 2018 due to being earthquake-prone, and is being demolished.
