Joanna Lam, 24, and boyfriend Connor Hayes are believed to have swept off the Haast Pass road by a landslide during wild weather on September 10.
Wreckage from their rented campervan was found in a flooded Haast River before a body believed to be Ms Lam's was recovered on Friday.
Her body has yet to be formally identified. There has been no sign of Mr Hayes.
Staff at Ottawa Hospital, from which Ms Lam was on a leave of absence from her position as sonographer, are pitching together to bring her home.
On the hospital's Facebook page, they remember her professionalism, personality and wonderful smile, which will be missed her her friends and colleagues.
"It is an incredibly difficult time for those who knew and loved Joanna."
And they urge donations to the Joanna Lam Memorial Fund, set up by the Ottawa Hospital Foundation.
The post says the money will ease the financial burden on Ms Lam's family as they deal with her death.
According to the post, which featured a photo of Ms Lam in blue scrubs, it will cost between NZ$17,500 and NZ$23,400 to bring her body back to Canada.
Any extra funds will be donated to the volunteer West Coast land search and rescue team that recovered Ms Lam's body on an unnamed stretch of coastal beach between Haast and Knights Point.
Up to 50 local volunteers, including whitebaiters, have helped with the search, on foot, jet skis and horses.
The search for Mr Hayes has been scaled back.
A dive team searched Haast River on Thursday but came up empty-handed, a police spokeswoman said.
Meanwhile, tourist operators have vowed to keep an eye out, while daily checks along the beach at low tide are being done by a volunteer on a quad bike.
