"Southern DHB commends the great work Bronwyn McBain has done, and the work which all the volunteers are doing in Sierra Leone to support their population health needs at a time of crisis," Dr Poore said.
Former New Zealand prime minister Helen Clark, and current head of the UN Development Program, said Kiwi health care workers in Sierra Leone have been doing "an incredible job" supporting the local health service response to Ebola.
"I met a number of Kiwi nurses when I was in Sierra Leone last month. They were with the Red Cross and filling critical skills gaps in local services, and were passionate about their work in the country."
Dr Poore said mother-of-two Mrs McBain will be welcomed back to work whenever she is ready.
"Southern DHB appreciates and commends her commitment to this international crisis," Dr Poore said.
"Southern DHB is offering support for Bronwyn and family as required."
Today, Mrs McBain declined a request to be interviewed and asked for privacy.
The only person to have contact with Mrs McBain during the infectious period was her husband, Gary, who has been self-monitoring as a precaution.
He did not return calls today.
Neighbours of the McBains in Ruia St, Gore, were woken by sound of a helicopter arriving early on Saturday morning.
Mrs McBain walked to the helicopter and was transported to Christchurch Hospital in a specialist iso-pod patient transfer unit accompanied by health care workers in protective suits.
Mr Coleman said Mrs McBain would remain in one of Christchurch Hospital's dedicated specialist medical isolation rooms until the result of the second test is known.
Mrs McBain previously helped in a tsunami ravaged region of Sumatra in 2005 and spent time nursing in Vanuatu in 2004 at her own cost.
