"This isn't going to be an easy journey for Cheryl [Maree's mother], Maree or their whanau but with huge hopes I really hope everyone can help them out in anyway possible big or small every little bit helps."
Wade said the first sign there was a problem was in early September when Maree had a fall.
Doctors discovered the cancerous tumour growing at the base of her brain. It had started to affect her motor skills.
"The tumour is called a pontine glioma [and] is on the stem of her brain which affects some, if not all, of her natural motor skills, affecting her speech, her balance and many other aspects of her life," she wrote.
Beating the cancer was going to be a major hurdle for the teen and her family to overcome, Karla added.
To help ease the stress on the family she had set up the Givealittle page to raise money for travel costs, accommodation and food.
