Northland sheepdogs expected to do well include Ken Whittaker's Doc (the current national long head champion), Scott McRae's Elle, Allen Nisbet's Maggie, Rhys Dacker's Speed, Murray Child's Dice and Ace, and Owen Finlayson's Lady.
Huntaways worth catching in action include John Nelley's Buster, Tony Comins' Shelley, and Murray Child's Frank, while Leo Jecentho's Pet and Cap and Storm from Te Paki Station are among a number of local dogs with the potential to record upsets.
The North Island champs started on Monday and ends Friday, with provision to run on Saturday if the weather packs up during the week.
Spectators are welcome at any time during the week-long champs; admission is free, with plenty of parking at the courses. Caterers are on site. The hosting Northland Sheepdog Centre headquarters is on Hariru Rd about 2km off SH1.
