Meanwhile, South Island cyclists are making their way north during the week, riding various stages - and avoiding main state highways as it was too dangerous for riders and too complicated to arrange with traffic safety management, organiser Peter Yarrell said.
This is the first event of its kind and has attracted media from Australia, Japan, Hong Kong, China and the UK who have come to ride in the tour.
After three stages, Japan's Dan Underwood was leading the individual tour, while Air Force Ohakea were the team tour leaders.
Air Force Ohakea are a corporate team of six personnel from Ohakea Air Base, who are celebrating 75 years of the Royal New Zealand Air Force.
To date, conditions in the North Island had been ideal for cycling, Yarrell said, - despite it being windy on stage one, leaving Cape Reinga.
