Mr Kitchen said he had been misinformed about the responses from Switzer and the RSA, the latter saying it would have helped but did not have a suitable vehicle. (Mr McFall's wheelchair weighs 170kg).
"We really need a database for situations like this," he said, adding that the problem had been compounded by the lack of a cell phone signal at the scene of the crash, "but that's another issue."
Mr McFall (52) said he had been on his way to Ahipara to complete one of his "bucket list" items by fishing on 90 Mile Beach when the engine in his modified vehicle cut out, causing the brakes to fail.
"There was no power steering either, and the car was getting quicker and quicker. I made a conscious decision to drive into the bank to stop," he said.
The vehicle came to a halt hanging over a steep bank, while a trailer with a modified four-wheel drive buggy for the beach remained on the road.
Following motorists removed Mr McFall and his caregiver, also confined to a wheelchair, from the car and moved the trailer off the road.
A couple continued to Kaitaia to get cell phone coverage to call emergency services, then returned to comfort Mr McFall, who was finally collected by friend Kevin Griffiths, from Ahipara, after the hospital bus operated by Kaitaia firm Harrisons Cape Runner had arrived and driver Craig Harrison was preparing to hoist him aboard.
