Earlier today, Prime Minister Jacinda Ardern confirmed the country would go into alert level four - and a full national lockdown - in the next 48 hours.
All of Government Controller John Ombler addressed a media conference, along with other key personnel involved in the response.
Ombler said it was clear there would be significant disruption to everyone, "but the alternative would be far worse".
"I'm confident that this all of government leadership is the best way to support the community.
"These are restrictions to save lives."
