"Engineering recommendations for additional strengthening during the consent process showed that repairing the existing roof to full code carried potential future costs and risks, which is not acceptable best practice for us and our construction partners.
"This move from repair to replacement of the west stand roof is a normal variation during this phase of a construction process and means we still get to deliver the vision of the best regional stadium in New Zealand."
He says it's exciting the Yarrow Stadium will be back soon as a functioning facility in time for winter sports.
"Despite disruptions caused by Covid-19 alert levels, our focus continues to be ensuring progress on all aspects of the Yarrow Stadium refurbishment and repair."
The project has received funding of $20 million from the Government's IRG Covid Recovery Fund.
Yarrow Stadium will reopen with a repaired west stand, new hybrid GrassMaster turf, and replacement LED lighting. The new east stand is set to open in 2024.
