The rowers' voyage has been hindered by extreme weather, broken equipment and injuries, and being confined to a 10.5m long by 2m wide boat with no home comforts such as a shower, kitchen, comfy bed or toilet had taken its toll.
"There were times we seriously didn't think we were going to make it," Cherrie said.
"There were a couple of discussions on board whether we had to head back to Australia at some stages."
On Saturday, the team rounded Cape Reinga and in the next two to three days they will berth somewhere south of Cape Brett to stock up on supplies.
To fuel the half-million oar strokes needed to cross the Tasman, the rowers consume a fat-rich diet of 8000 to 10,000 calories a day but each will still lose about 20 per cent of their body weight.
To maximise their speed and efficiency, the rowers have been working in shifts with two hours at the oars and two hours off to replenish.
