A specialist told Ms Goodall and her fiance, Mathew Gray, that 8-day-old Hunter's liver was failing.
Later that day, doctors made the decision to put him on life support after his kidneys began failing and he began having seizures.
Doctors discovered the herpes simplex virus, or the cold sore virus, on the morning of May 20, and it baffled Hunter's parents.
Doctors said it was incredibly rare for Hunter to contract the virus, which is not usually contracted by babies delivered by a Caesarean, as Hunter had been.
Ms Goodall is full of praise for the staff at Starship who did everything they could to save her son.
"Mathew and I only slept one hour each night. Doctors and nurses are there 24/7, there was never a time that they weren't there, they are really dedicated," she said.
"After he passed away, they made moulds of his hands and feet, they took photographs, they christened him, kept locks of his hair and made a book we could take away.
"That is really important - that is all we have got."
The Transport Syringe Pumps that Ms Goodall is fundraising to buy Starship are able to accurately deliver drugs to critically ill children. Because Starship PICU sees very small babies, it needs the machines to access tiny veins and deliver drugs smoothly and relatively pain-free.
In the PICU at Starship, 11 of these pumps, each costing over $4000, are required.
"Hunter used one of these pumps so I know first hand how important they are," Ms Goodall said.
"I feel that for part of my healing and to help other sick kids have the best possible chance of living and running around with brothers and sisters I would like to buy Starship one of these pumps."To support the Starship Foundation and to donate to Ms Goodall's cause visit: www.fundraiseonline.co.nz/HuntersPage
