So Frank and Wilma did what many people would do - they made every day count.
Frank, who used to own a handyman business in Auckland, gave away $30,000 worth of tools, fishing gear, a quad bike, clothes and household items. They sold their house in Wairoa at a loss of $70,000 and cancelled the health insurance.
Frank began smoking cigarettes and drinking coffee after quitting during his first cancer diagnosis.
The couple went to Fiji for 10 days. They blew $30,000 on food, a five-star resort and fishing activities, expecting his life insurance to cover the costs.
"We had a good time. We spent too much money on food, going around New Zealand and then a business which fell down," Wilma said.
"What would you do in this situation? If he said jump I would jump ... I was putting him first, whatever he wanted, he got.
"I'm short on my credit cards for $80,000 and the money we had left went on a business and that didn't work out so we are broke."
On their way home they stopped off in Australia to visit their daughter and two grandchildren.
Then they headed back to Wairoa and waited for Frank to die. Every morning Wilma would get up wondering if today was the day.
But every morning Frank would be feeling fit and healthy. His weight remained the same and his health was not deteriorating as predicted by doctors.
"If the pain got too bad I was going to kill myself, but the pain never came ... everyone was surprised I was still alive," Frank said.
It was not until their hospice carer came for his monthly check-up - 23 months after Frank was told he was on his way out - that they discovered the terrible mistake.
"He said, 'I'm here for the last time', and I said, 'Why'? He said, 'Well you don't have cancer'. We looked at each other and he said, 'Don't you know'?"
Frank had had another ultrasound test in December 2011 - and this cleared him of cancer. But it was not until the hospice worker told him in February that he knew he was in the clear. They don't know why the hospital didn't tell them earlier.
The hospital has acknowledged it made an error, but says it made the right call based on the evidence at the time.
"The consensus at the time from all the doctors, including the oncologist involved in Frank's care, was that, sadly, there was a high likelihood or little doubt of a recurrence of the lung cancer," Hawke's Bay Hospital respiratory physician Dr Rob Armstrong said in a statement. "In this instance, thankfully, we were wrong but we can't yet rule out a recurrence of cancer in the future."
They had based that on excessive fluid and blood around his heart, an initial ultrasound result and his previous health condition.
"Occasionally where diagnosis is difficult and complicated by other medical conditions, like in this case, we can be wrong."
Wilma said they've lost faith in the health system and refused to get medical care.
A claim has been lodged with ACC and the error is being investigated by the Health and Disability Commission.
