"The closure of construction sites will inevitably result in delays to the completion of Commercial Bay and Wynyard Quarter. While the cost of the delay will depend on the duration of the closure, Commercial Bay is close to completion which will help limit the impact of the interruption," the company said in its trading update.
While the impacts of COVID-19 continue to evolve, we will continue to actively implement our business continuity plans to ensure the right procedures and suitable precautionary measures are in place to help protect the health and well-being of all our people, while also restricting any potential negative impacts on the business.
