She spent nearly two weeks in Waikato Hospital before being transferred back to Rotorua Hospital last week.
Doctors have told the family that although she has turned a corner, she is not out of the woods yet and could face life-long scarring from the sores.
The Owhata school, Owhata Friends of the School and EBabies Early Learning Centre are holding a fundraising family day at the school this Saturday to raise money for Valencia to help her recovery and to support her family.

Her family, who have five children, have had a tough time in the past few months, with her father, Karamana Mikaere, being made redundant with the closure of Lumbercube and her mother, Ene Mikaere, being off work from her job at Countdown to be in hospital with her daughter.
Mrs Mikaere said yesterday that she couldn't thank everyone enough for all the messages of support.
"I got two really helpful responses from two ladies who both had their daughters affected with the same thing, adding me to SJS groups and just giving me tips on what to keep a close eye on.
"One of the daughters was a patient in Rotorua Hospital, she was 15 and the very first case they had here."
Mrs Mikaere said the online comments via the Rotorua Daily Post had blown her away.
"The response has been so overwhelming, I try and keep up ... I think I've read each and every one of them to my daughter. Total strangers, sending their thoughts and prayers, simply amazing ... We are so very grateful."
Eleanor Mahaki, who is organising the weekend's fun day, said she too had been blown away with support and her phone had been ringing hot.
Today she picked up a cheque for $100 and prizes for raffles from a 94-year-old woman who didn't know the family but was affected by their story.
The fundraising day will run from 10am to 2pm on Saturday.
