Spectators at Northland's Bayleys Southern Districts, Bay of Islands, and Mangonui premier competitions can expect a few changes as matches get underway this season.
However, Northland Rugby Union officials say they shouldn't be alarmed.
Incorporating several new Mitre 10 Cup playing laws into the competitions from round one, the new laws will be foreign to most punters, especially those who have been following Super Rugby.
"If you're going to Bayleys club rugby this weekend, there are new trial laws at the breakdown," Northland Rugby Union chief executive Jeremy Parkinson said.
