He said there was still a "strong link" to overseas travel.
He said of the 455 cases that the Health Ministry had sufficient information, 57 percent have a direct link to overseas travel, 26 are close contacts with existing cases, 15 percent have both, and just 2 percent - or about 10 cases - are currently community transmission.
Dr Bloomfield said contact tracing was a work in progress but capacity was increasing - it sometimes took six to seven phone calls to try and contact someone.
He said flu vaccinations were going to a vital part of the fight against Covid-19.
"Because if we vaccinate people, then we can reduce pressure on our hospital system, particularly through winter."
He said it was "very important" that vaccinations were being reserved for high priority groups - over 65 and those with likely health complications.
He said those not in the group should not expect to be vaccinated before mid-April.
Dr Bloomfield has asked New Zealanders to register with Flutracking for surveillance of Covid-19.
Police Commissioner Mike Bush said two police staff had tested positive for Covid-19. They are at home and had not been hospitalised.
Several hundred police officers around the country are in self-isolation as a result.
