There's a call for anyone concerned about Covid-19 to get a test, even as a surge in testing increases the turnaround time for results.
In a statement, the Lakes District Health Board said it been told there may be a delay for some results because of the "very large volume" of tests locally and nationally.
Results were expected back in 72 hours compared to 24 to 48 hours before the Lakes' first positive case of the Delta outbreak was found in Taupō on Saturday.
By the end of the weekend, there were four cases in Taupō and two in Rotorua.
On Monday, 1016 Covid-19 swab tests were taken from locals compared to just 177 the previous Monday.
A Lakes DHB spokeswoman said it had a surge plan it could implement that entailed making sure staff and facilities were available should there be a need to increase testing in Rotorua, Taupō and Tūrangi.
There were 15 cases in the Lakes DHB area, with no new cases announced yesterday. The neighbouring Bay of Plenty DHB area had its first confirmed cases of the Delta outbreak in Mount Maunganui and Tauranga.
Lakes DHB chief executive Nick Saville-Wood said some cases were not showing any virus symptoms and encouraged anyone who was a contact of a case, had been at a location of interest or was concerned about the virus to get a test.
"Testing numbers have dropped off dramatically after the first two days [post confirmed case]. I encourage people to go and get tested," he said.
Saville-Wood said that as long as the virus was contained, quick action was taken with new cases and the vaccination rates rose to 90 per cent there were reasons to be optimistic.
"The cases in Taupō are all linked and we have established that which is good. We just need to keep testing."
University of Canterbury professor and Covid-19 modeller Michael Plank said it was "hard to say" how much the virus could spread.
"It depends very much on how much those cases have been in the community, how many contacts they've had and whether those contacts are vaccinated or not," Plank said.
"If [the case has] largely been in contact with vaccinated people and live in a high-vaccination area, it's possible this won't go anywhere - it'll fizzle out. We've seen that in Christchurch recently. If it's a low vaccinated community there's a higher risk it'll establish and generate further spread."
Plank said it was important people kept an eye on locations of interest and continue to sign in wherever they go so they have the tracing information available.
In the Lakes DHB, 85 per cent of the eligible population had received their first dose and 75 per cent were fully vaccinated.
Sixteen locations of interest had been named across the Lakes DHB area as of 5pm yesterday. There were none in the Bay of Plenty DHB.
Rotorua MP Todd McClay thought there would be more cases in Rotorua.
"It is inevitable. Waikato has a large number of cases per capita and with the soft border coming down people are able to move freely."
Rotorua Chamber of Commerce chief executive Bryce Heard said he thought everyone knew Covid-19 would spread throughout the Bay of Plenty region.
"I think we all knew it was coming. Covid appears to be steadily and remorselessly creeping through the country."
Meanwhile, Red Stag Investments Limited managing director Jason Cordes said a team member of Red Stag Wood Solutions, who lives in Taupō, tested positive on Monday. The result was confirmed on Wednesday.
Cordes said the person came to work in Rotorua on Monday and notified management that they were a close contact. They were told to leave immediately and get a test.
The person works in Rotorua but does not live there.
Anyone who travelled and lived with this person had been tested and received negative results, Cordes said. The ministry estimated the possible time of exposure to parties from Rotorua was approximately half an hour.
"We've been told there is a low risk of contagion," Cordes said.
