Hon Dr DAVID CLARK: All PHUs are submitting contract tracing data to the National Close Contact Service, and this information is collated to produce national monitoring indicators. All contact tracing delegated to the National Close Contact Service by PHUs is being done through the National Contact Tracing System. All PHUs are required to provide information to the ministry for national monitoring, which has enabled the ministry to meet the requirement in Dr Verrall's report for national end-to-end contact tracing indicators.
