"There was some good batting from our top order and put a good score on the board. I might have got a little bit lucky but a lot of us bowled pretty well and got the job done in the end," Boult said.
"It is always challenging coming back after a little time off in to a team with pretty good momentum and everyone's doing pretty well. To come in and contribute to a win is the main thing."
With his first delivery Boult had a huge appeal given not out against Tilikaratne Dilshan for caught behind. The Black Caps went upstairs to third umpire and former Tauranga boy Billy Bowden, who made the decision to send Sri Lanka's most experienced batsman back for 0.
"Dilshan is obviously a massive wicket for them so it was nice to get him early on and then everyone put pressure on after it was set up nicely by a pretty good total," Boult said.
Boult's mate from intermediate days, Williamson enjoyed two wins captaining the Black Caps this week.
"There are a lot of new faces I guess swapping formats," Boult said. "Kane is doing well and I can imagine it is a very tough job with how fast the game goes. You have 120 balls to think of all these outcomes and stuff. I hope he is enjoying it."
They leave behind two unforgettable days of cricket played at a venue NZ Cricket must surely be considering for international cricket every summer.
On what was served up this week the Bay Oval deserves nothing less.
