What we're working on:

COVID-19 Simulation Tools

We are helping the New Zealand Operations Command Centre with COVID-19 simulation tools for planning the all of government response. This is a complex multi-discipline problem. Our mathematicians, data scientists, software developers, testers and support staff are helping minimize the impact of this terrible disease on New Zealanders. 

Some of our research work is public domain and you can read it on our COVID-19 blog.

Check back occasionally as we share information important to reducing harm.

But remember to wash your hands often, cough or sneeze into your elbow and follow the guideline published here. But most of all stay safe and look after each other. We are all in this together.
