Bad weather and a foot infection are making an ambitious journey from Sydney to Auckland by sea even more challenging for four New Zealand rowers.
The expected 30-day trip may now take up to two months for Team Gallagher Tasman, who are in their 25th day on the Tasman Sea.
The Kiwis have spent the past two days retracing their path after being blown northwest.
They have spent about eight days anchored because of the weather and have been a man down since Friday.
Lincoln University economics professor Martin Berka, 37, has been battling an infection in his right foot which made it impossible for him to row. He has been injecting antibiotics and keeping a close watch to make sure the infection does not spread up his leg.
