Where are the cases?
==================
The latest data from the Ministry of Health shows that the Southern District Health Board (DHB) continues to have more cases of COVID-19 than any other DHB, with 207. It's followed by Waitemata, Auckland, Waikato and Canterbury. Tairawhiti continues to have the fewest with only a single case in that DHB. The Ministry of Health website doesn't break the data down into individual towns or areas, however, some DHBs are providing more specific information on their websites.

Transmission
===========
New Zealand is now in its third week of nationwide lockdown under alert level 4. The decision of whether to extend that lockdown from its currently four-week run or to lift it will be made on April 20. One of the key pieces of data that will be considered if the level of community transmission, which is where officials can't identify who an infected individual contracted the illness from. That is up 1 percent on last week, while transmission overseas has fallen.
Transmission type
===============
Overseas: 40 percent
Contact with known case: 46 percent
Community transmission: 2 percent

Clusters
=======
Outbreaks within New Zealand may be referred to as clusters. These are groups of COVID-19 cases linked together as they have all been to the same location. Within a cluster there may be an individual who has a link to someone who has travelled. The number of cases linked to clusters has grown over the last week with the increase in the "contact with known case" transmission type. There are 13 significant clusters in New Zealand.
These are clusters with 10 or more cases.
