The All Whites burst from the traps with points from player of the match Siobhán Hurley and 18-year-old Melissa Lyons inside two minutes.
Susie O’Carroll, Róisín O’Connell and Hurley (free) added to their tally before a Louise Mahony free opened the Laois account in the 24th minute.
Kildare had only a four-point lead to show for their efforts at half-time (0-6 to 0-2).
Laois fired a 32nd minute goal from substitute Grace O’Neill, whose powerful shot dropped inside the upright past Saileóg O’Keeffe.
Kildare then upped the gears with star full-forward Susie O’Carroll hitting two goals in a minute. The first came after good work from O’Connell and Lyons, and the second, saw the Celbridge sharpshooter read a long delivery best before drilling a shot beyond Laura Dunne.
Hurley and Lyons added points and though Mahony slotted a couple of frees, Laois never looked like getting the goals they needed.
