Find out how Contact Tracing works in New Zealand to track cases or known links to cases that are either called casual contacts or close contacts. The process in this video shows you how COVID-19 has made the Ministry of Health develop a way to trace people to reduce the spread of the virus.

The Group Manager for the National Investigation and Tracing Center (NITC) Astrid Koornneef, was with her team on Wednesday in front of media, to help showcase and explain the system.

“I have bought my team here today to take you through a little bit of detail around contact tracing and explain the process. And, we will follow that by a demonstration of the national contact tracing solution, which is the IT system that supports the pathway for contact tracing so that includes the public health units, ourselves and many of our contact providers”

The Chief Clinical Advisor for the National Investigation and Tracing Center (NITC) Matthew Reids is playing a big role also in contact tracing.

“How we can see the contact tracing is it starts with a case. So, contact tracing is all about getting the contacts of that case into quarantine to reduce the risk that they are going to pass COVID onto another person, and in order, that we could manage any risks to their health.”

Matthew Reid explains how the system works when someone either catches COVID-19 from someone else or even as an imported case in managed isolation. 

Here is how the process works:
* The person undergoes a COVID-19 test
* ESR (Institute of Environmental Science and Research) records the result as notifiable disease respiratory (EpSurv) and then the record enters NCTS/C (National Contact Tracing Services/Center)
*
Then the Individual will be informed of the result (if confirmed or negative) – health assessment and advice is then given –> the individual will receive isolation support and outreach services
* The case then goes under investigation to obtain more information about close and casual contacts that may be at risk
* Close contacts will be contacted and then asked to get tested and self isolate to reduce the spread of the virus –> the individual will receive isolation support and outreach services

* Any close contact will be followed up, by being contacted daily to ensure the contact is doing okay, checking up on anything health-related and making sure health needs are met –> the individual will receive isolation support and outreach services

The Lead Analyst for the National Investigation and Tracing Center (NITC) Claudia Rees explains in-depth how the training environment for contact tracing works.

“Our training environment is available to all users to practise case investigation entry and close contact follow up and data entry. It helps us to get familiar with new things happening in the system, as we are always improving the system — things change so we get the training environment to practise things and use it to become better at using it.”
