The hosts came back though as the half wore on and Meyler slotted a penalty after Adam Byrne was pinged for holding-on in the tackle.
The home side had a couple of chances to score a try of their own but the pedestrian pace of their backline meant Leinster were able to fan across and snuff out any danger.
Sean O'Brien had a try correctly chalked off due to a knock-on in the build up and the teams went into the break with the visitors leading 10-3.
Northampton stormed out after the break doing to Leinster what the Irish side had done to them in the first half.
An excellent break from JJ Hanrahan, was recycled and Hanrahan floated a precise pass to Tuala who dotted down in the corner. Myler converted from the touchline to tie the scores at 10-10.
Nacewa slotted a long range penalty after Tom Wood was pinged for coming off his feet to make the scores 13-10 to the visitors.

Dylan Hartley's introduction to the home side didn't have the impact the Saint's were hoping for. His side gave away two scrum-penalties before recklessly throwing an open arm at Sean O'Brien's head.
