All Northland adults who enter the event will also go into the draw to win a Mazda 2, which will be drawn two weeks after the final event in the series, the Kerikeri Half Marathon, in November.
The final two events in the series are the Whangarei Half Marathon and 9km Run/Walk on September 18 and the Kerikeri Half Marathon on Saturday, November 19.
Organisers said the first three events in the this year's run/walk series were dominated by top Northland runners, Harry Linford and Carolyn Younger.
However, with both unable to compete in the Baylys 2 Dargaville Run/Walk in June, the event leaderboard is now wide open with an opportunity for Whangarei's Katie McVerry and Warkworth's Louis Young to climb to the top if they win their respective sections at the Kaitaia event.
Sport Northland spokeswoman Colleen Atchison said organisers were rapt to announce a local business had claimed the naming rights for the Kaitaia event.
"Sponsorship makes it possible to stage events, so we are grateful, not only for Toll's support of the Kaitaia event, but for all the extra help and assistance they give to Sport Northland," she said.
Entries for the Kaitaia Run/Walk will close on Wednesday, August 10.
