"We were able to essentially stamp out Delta. With Omicron, we won't be able to do that," PM Jacinda Ardern said of the current outbreak.
Even in the best case scenario for Omicron, there's going to be huge pressure on already busy hospitals, a leading emergency doctor says.
Latest numbers by Covid-19 Modelling Aotearoa suggests a peak of 800 people in hospital on any given day at best,but well over 3000 at worst.
There was growing optimism the country would achieve the lower hospitalisation numbers - as long as people kept getting boosted and restrictions stayed in place.
But College of Emergency Medicine head John Bonning said that would still mean a big few months for emergency departments.
Many had been extremely busy with normal work in the past few days, and having Covid-19 on top of that would be a big stretch.
The impact would be felt even more with the inevitable short-term loss of staff who would become infected themselves, he said.

"We are very busy and very full of a lot of people with non-Covid illness and so it is going to be tough, and particularly in emergency departments," he said.
Although there would be a huge amount of pressure for people working in health, care would still be there for those who needed it.
"I don't want to put people off coming to emergency departments when they have terrible chest pain, or they're having a stroke, or they're haemorrhaging or they're elderly and they fall," he said.
He urged people to get boosted to keep themselves safe and to help keep hospital numbers low.
One of the modellers, Michael Plank, said he was also optimistic New Zealand would flatten the Covid-19 curve - as long as people kept getting boosted in big numbers.
His team had investigated three main trajectories - the path of South Australia in the best case scenario (a peak of 800 people in hospital on any given day), London in the middle (resulting in a peak of 2100 people in hospital a day when applied to New Zealand), and New York in the worst (a peak of 3300 per day in hospital).
All of those figures assumed a 90 per cent boosted eligible population, with the figures considerably worse if just 70 per cent took up the booster.

Plank said the most likely scenario was South Australia, or a mix between South Australia and London.
"If we can really keep the momentum going with boosters and we continue the momentum with the 5 -to 11-year-old vaccinations then we stand a really good chance of avoiding some of the worst outbreaks we've seen in other countries," he said.
"But I am still worried about the amount of pressure that our health care system could have during the peak of the outbreak, so we can't afford to be complacent.
All the measures to slow or flatten the curve were still crucial, he said.
The modelling had predicted a range of deaths with scenarios from about 400 to about 1400.
Plank said that was the least certain factor in the modelling because fewer people had died from the variant, so there was less statistical evidence to base the modelling on.
