Hon CHRIS HIPKINS: Yes. Contact tracing is one of the key pillars of our defence against COVID-19 and other infectious diseases. Today's announcement included a $30 million investment in the National Close Contact Service, including for surge capacity and information technology. A related information technology project will see the development of a new national immunisation solution to replace the immunisation register, meaning that we're ready to roll out a mass vaccination campaign when a COVID-19 vaccine is available.
