Last season's finalists had very different starts to their campaigns.
Clough/Ballacolla got off to a losing start in their hunt for four Laois Hurling Championships in a row with a four point loss to Rathdowney-Erill on Thursday evening.
Ross King ended with an impressive 0-14 to get their campaign off to a flying start.
On Saturday evening, Rosenallis began with a 2-14 to 0-17 win over The Harps in O'Moore Park.
Two second half goals from Charlie Friel and Jimmy Hyland made the difference, with David Dooley also having a huge say with 0-10.
Elsewhere, in Group B, last season's beaten finalists Camross began with a comfortable win over Castletown on Wednesday night.
Tomas Keyes was the main man as he tallied an impressive 2-05 in helping Camross lay down an early season marker.
And finally, Abbeyleix St Lazarians and Borris In Ossory played out an entertaining encounter, with Abbeyleix leaving with a three point win.
Goals from Ciaran and Colin Byrne made the difference, as Abbeyleix secured a 3-13 to 2-13 win.
The next round of fixtures will take place in two week's time.
