There's been school visits, mayoral receptions, a bit of wild weather and even a spot of mechanical trouble, but three tractors tasked with a momentous journey from Auckland to Aoraki to raise money for Sir Edmund Hillary's Hut are almost a third of the way there.
The two vintage tractors similar to the Ferguson TE-20 models used by Sir Ed to reach the South Pole in the late 1950s, and a modern Massey Ferguson MF5600, have been turning heads and drawing crowds as a team of four drivers make their way slowly from Piha Beach to Aoraki Mount Cook.
Dubbed "Expedition South", the month-long road trip was launched by the Antarctic Heritage Trust to help raise $1 million to repair and maintain Hillary's Hut, the first building at Scott Base and the launching pad for the famous Trans-Antarctic Expedition of 1957-58.
Executive director Nigel Watson said Expedition South was now in its 10th day and had arrived in Whanganui today at 4pm.
So far the expedition had covered 600km, almost a third of the 2012km - the same distance Hillary and his team travelled in the coast-to-coast crossing of Antarctica - and raised nearly $4000.
