Ireland’s women recovered from losing their opening game in the Rugby 7s against Great Britian to beat South Africa 38-0 at the Stade de France.
Beibhinn Parsons scored the opening try under the posts after being found by Erin King.
Captain Lucy Mulhall Rock was accurate with the conversion but then went off injured before half-time.
Amee Leigh Murphy Crowe registered Ireland’s second try just a minute after the break, dotting down after good work from Megan Burns.
Parsons then twice crossed the whitewash to add another two tries as Ireland began to run riot.
Vicki Kinkan touched down at the left-hand corner before Eve Higgins rounded off the scoring with a late try.
They are back in action tomorrow with their final Pool B game against Australia.
