"At this time of the season, a lot of the training is longer, endurance-length stuff and it can be a pretty hard slog for athletes trying to get through these colder months," Bicknell said.
"Introducing the winter series is a great way for them to measure their progress and also to get some good, hard racing at this time of the year, although we'll be catering for all levels with our events."
Bicknell is confident of attracting athletes from across the North Island for the series, which will also feature events in August and September, before the spring series kicks off.
The first event will feature either a 9km or 6km ski option, board races and beach running events, from under-16 level right up to masters.
All points from the three rounds will be counted and prizes awarded to each respective age group, both male and female. Spot prizes will be awarded at the end of each round.
Racing starts at 9.30am on Sunday at Mount Maunganui's Main Beach, with Pilot Bay an option in inclement weather.
