A resident at Atawhai Assisi Home and Hospital on Matangi Rd has tested positive.

A resident at a Hamilton rest home has tested positive for Coronavirus, sending 27 staff into self-isolation.

The man, who's a resident in the hospital care section of the Atawhai Assisi Home and Hospital on Matangi Rd, received a confirmed positive test on Sunday afternoon.

Thirty-six new cases of coronavirus were confirmed in New Zealand on Monday, bringing the total number of confirmed cases to 102 with two possible community transmission cases.

"A resident has tested positively," Tamahere Eventide chief executive Louis Fick told Stuff on Monday.

Atawhai Assisi Home and Hospital has 86 beds at its Newstead facility. It is run by Tamahere Eventide which houses a separate home and village in Tamahere.

The resident had his daughter visiting from Australia around March 10, Fick said.

She returned home to Australia and had to undergo a test before returning to work as a nurse, he said.

"We were informed and began testing immediately and that was confirmed on Sunday."

Fick said the man was not symptomatic but was tested on Friday after the rest home was made aware of his family member's positive test.

He was put into immediate isolation in the hospital care unit of the rest home but is in a stable condition and being monitored continuously.

"The person isn't sick, he has no temperature and appears fine."

In response to questions over the case at Monday's daily Covid-19 press conference, Director-General of Health Ashley Bloomfield said this was expected in some cases of close contacts and that is why rigorous contact tracing and isolation of confirmed cases was being undertaken, and testing where necessary.

"Looking at the data internationally some people have a very mild or sub-clinical illness, especially children, so there will be people who we test because they are close contacts, they maybe very mildly symptomatic, or very early on in the disease and may test positive."

The rest home immediately stood down 27 staff that had been in contact with the resident and they were now in self-isolation.

Four of the rest home residents, in the hospital facility which houses 43 residents, were also in isolation as they may have been in close proximity with the confirmed case, Fick said.

He could not elaborate on what type of contact that resident had with other residents in the week before he was tested.

All residents were being closely monitored and staff were wearing personal protective clothing and following Ministry of Health guidelines.

"We have tracked the whole roster to see who worked with him and have a large number of staff self-isolating.

"It is in the hospital section so is only affecting half the rest home."

Fick said it was up to the Ministry of Health as to whether those staff were being tested.

"They have had to track who has been in contact and see if anyone else is affected."

A no visitor policy at both its Assisi rest home and the Tamahere care facilities had been in place since last week, Fick said.

"We've contacted all families, all staff, to inform them of what's happened. Staff are generally anxious and we're doing our best to manage the situation."

Cleaning protocols for an "outbreak" had been undertaken, he said, along with strict regular cleaning of surfaces, handrails, floors and other facilities.

The rest home had been liaising with the DHB around protocols.

On Sunday the Waikato had nine confirmed cases with further details of the latest 36 cases expected to be released on Monday afternoon.
