Fellow tour guide Kelsey Waghorn has received more than $64,000 in donations on her Givealittle page.
Waghorn, a marine biologist, is described on the page as a strong, courageous, young woman who is "fiercely protective of those she loves".
"Be brave, we are all rooting for you," and "Kia Kaha Kelsey" are just some of the messages that have been shared on the page.
One donor said they went to school with Kelsey and "she is a bright and beautiful being".
Australian vet nursing student Krystal Browitt, who was holidaying onboard Ovation of the Seas, was also on White Island when the volcano erupted.
She was officially listed as missing by New Zealand Police earlier this week, while her father Paul and her sister Stephanie have both been hospitalised.
Browitt's mother, Marie, was unharmed by the disaster, having opted not to tour White Island and remaining on the cruise liner that day.
A Gofundme page created to support the Browitt family has raised $46,000.
A GoFundMe page appealing for funds for American newlyweds Matt and Lauren Urey has reached more than $20,000.
The couple were on the cruise for their honeymoon, and had gone to White Island for a hike.
Sydney couple Nick and Marion London have been flown back to Australia for treatment but face multiple surgeries and weeks, possibly months, recovering in hospital.
Both have burns to 50 per cent of their bodies along with internal burns from breathing toxic chemicals.
Son Matt paid tribute to the pair as incredible parents, saying dad Nick is a "gentle giant" and rock of the family, and mum Marion is filled with kindness and love.
