Her grandfather, "Poppa" Keith Hatwell, said fundraising for Skyla's bucket list was urgent while she was well enough to cope with the adventures.
"We've got her in quite a stable state at the moment but we don't know how long that's going to last."
Skyla's cancer was discovered after her father Jamie Hatwell became concerned when she began "stumbling around" following a school visit.
Doctors initially diagnosed an ear infection but a follow-up visit to Tauranga Hospital revealed the brain tumour. After being admitted to Starship for more tests, she was diagnosed with Diffuse Intrinsic Pontine Glioma.
Skyla's family set up a Givealittle page and $13,000 was raised to help cover the cost of alternative methods when medical treatment was limited to radiation.
But the funds have depleted to $1060 as Skyla received a range of alternative therapies costing at least $1000 a month. Mr Hatwell said he and Skyla's father believed the treatments had prolonged Skyla's life. Skyla's sixth birthday is approaching in September.
Mr Hatwell said the family were preparing for the worst but holding out hope for as long as possible with their precious girl.
