He told the medical staff he expected an ambulance would take him, as the trip was urgent and he had no funds.
"The doctor said 'nah mate, we can't do anything for you here'. They said if I didn't go I would catch an infection in the bone.
"They told me they didn't have the resources. They said I should ask my mother, or go to Work and Income," he said.
"It was like they were telling me to hitch a ride without a thumb but they used technical words. It was shocking."
Mr Renata said WINZ gave him a non-recoverable grant of $60 to fuel his family vehicle, which his partner Waitai Morete drove to Lower Hutt.
A similar grant paid for his son's travel to the specialist unit a year earlier, he said, but he was not advised at Wairarapa Hospital about his eligibility, or otherwise, to claim help through the Ministry of Health National Travel Assistance scheme.
Mr Renata and his partner arrived at Hutt Hospital about 2.30pm and he was wheeled in to the operating theatre about 4pm, he said.
He must again travel to Hutt Hospital for treatment on Monday, he said, and any further surgery will depend on the skin grafts taking or "they might have to cut off the whole thumb".
Wairarapa DHB spokeswoman Jan McLaren said the injury to Mr Renata was caused in an accident and ACC covered the costs of travel for treatment during the first 24 hours after the injury was received.
He was consequently ineligible for National Travel Assistance.
It was usual for people with injuries like Mr Renata, and his son last year, to be told to arrange their own travel if treatment elsewhere is needed.
"This is consistent with an assessment of clinical condition and hospital protocol. Transfer decisions are made around patient condition and support available. In this case the situation was not critical and the patient did not require a hospital transfer by ambulance or helicopter."
Mrs McLaren said Mr Renata had been handed an ACC form to claim the travel and the same procedure was followed at health boards throughout New Zealand.
