Northland's Roller Mills team may have tasted defeat for the first time but they still remain in second place, after going down 17-7 to North Harbour in Silverdale.
Despite the loss, the side sits in a handy position as they head into this weekend's final pool game against Auckland West in Dargaville - before heading to Tauranga for the finals weekend over October 4-5.
Northland were first on the board on Saturday, continuing on from their dominating 48-5 win over Thames Valley last weekend, through the efforts of Anton Weight who dotted down.
Kaleb Harema converted Weight's try, giving the Northlanders a 7-0 advantage early. However, North Harbour fought back and eventually took the game - scoring their first win of the season in the process.
While Weight scored Northland's only try, it was Grizzlies player Liam Harding who picked up the player of the day award.
