University of Canterbury Covid-19 modeller professor Michael Plank says 100 Covid-19 patients going to hospital a week is a "likely scenario" by early next month.

At the current spread, he is predicting about 150 cases a day by early November.

That's 1000 cases a week.

Plank predicts 10 to 20 people a week could need intensive care.

In the past seven days, there have been 300 community cases - an average of 43 a day.
