The December 9 disaster killed 19 people, with two bodies yet to be recovered, and injured 28 more people.

Ms Pyecroft offered her skills and has been helping in Whakatane Hospital in the country's North Island since New Years Day.

For a number of years the emergency nurse lived in NZ in Katikati in the Bay of Plenty, only 1.5 hours north of Whakatane which is one of the main tourist access points to the volcano.

Ms Pyecroft said everyone in her life, from her family to the LGH, was very supportive when she found out she was chosen to assist.

"I volunteered to come to Whakatane for several reasons," she said.

"Firstly because I know the area very well and take pride in knowing a fair bit about the Maori culture and how family orientated they are...they look after one another and are very community orientated.

"When the request came to assist the staff at the hospital I knew that they really needed some assistance and I was more than willing to give them assistance knowing what they had been exposed to that day White Island erupted.

"It is with great pride that I'm here in NZ, representing the LGH emergency department, Tasmania and Australia."

She is the only Tasmanian nurse out of seven assisting in the emergency department until the end of January, to take pressure off of the staff dealing with the disaster's trauma.

One nurse is from NZ's south island and the six Australian nurses were chosen through Australia's National Critical Care and Trauma Response Centre.

Ms Pyecroft said the town's hospitality had been amazing since they arrived and the community had been very welcoming despite still being in mourning.

"The hospital staff have just included us just like we've been here all the time," she said.

"The community has been amazing too...people in the community come up and just say how grateful they are we came out to help at their little hospital.

"It's a big holiday place and they were a bit worried the tourists wouldn't come after the disaster but they did."
