An expert who's been watching how many Kiwis are using the Covid tracing app says while the numbers are up - still more people need to record their movements.
Today the Director General of Health Dr Ashley Bloomfield said the app has had 100 million scans.
Over the long Labour Weekend, there were 850 thousands scans per day.
This is up on the regular average of six hundred thousand.
However, Dr Bloomfield has called for people to increase their use of the app.
Dr Andrew Chen is from Auckland University's Centre for Informed Futures - Koi Tu.
