Late on Tuesday night, Prime Minister Jacinda Ardern said it was necessary to go hard and go early to stamp out the virus.
Auckland residents have been asked to stay at home,. On top of this, large gatherings are banned, non-essential businesses must shut, and social-distancing guidelines must be followed.
The rest of New Zealand has been placed into Alert Level 2.
