They've beaten the Canterbury Bulldogs 40-6 in Auckland, with Keighran scoring 16 points of his own.
However coach Stephen Kearney says Keighran, like the whole team, can still get better.
He says it was a good start for him, but there's plenty of room for improvement.
Meanwhile, the Tigers have beaten the Sea Eagles 20-6, while the Cowboys dispatched the Dragons 24-12.
