Here's the graph for Monday 20th April from Chris McDowall | The Spinoff

Updated plot shows local cases decreasing when plotted against 'Date of report'.  Same for total cases, as per frankv plot above.   

Well, this is a good news day. NO confirmed cases yesterday, just two probable. Of course, that may change retrospectively whenever today's tests' results come back. :)

There were two confirmed cases announced today and listed on the MoH site...very promising trend however

Here's the graph for Monday 21st April from Chris McDowall | The Spinoff

Update of plot. 

Note that the six new cases announced in the press briefing today included only 4 with a 'Date of report' being yesterday (3) or this morning (1).  The other 2 cases were from 16 Apr and/or earlier dates (some +/- with net of +2).  So down to just 3 (local & total) with a 'Date of report' = 21 Apr (yesterday).  The 1 case for 'today' is just what MOH received before 9 am so will very likely change in tomorrows data.

Second day of no new confirmed cases. :) I've made a small change; from now on the predicted cases are zero, for the purposes of calculating the last 4 points on the 7-day moving average graph.

These graphs etc are very informative, but why is there a discrepancy between the Active Cases number above and the official number of 401?  Or have I mis-read the graph?

Paul1977: Where can you get historical data by region? I’d like to look at the case history in my local region but can only find the current numbers.

DHB region info is available in the individual case data 

https://www.health.govt.nz/our-work/diseases-and-conditions/covid-19-novel-coronavirus/covid-19-current-situation/covid-19-current-cases/covid-19-current-cases-details

If you let me know which region you are interested in I can filter for that
