The New Zealand opening batsman Martin Guptill says it was very satisfying to score a hundred.
Guptill scored his third Test century and first in four years to help the Black Caps to 409 for 8 on the first day of the opening Test against Sri Lanka in Dunedin.
He and Kane Williamson, who made 88, put on 173, a record second wicket partnership for New Zealand against Sri Lanka and bettering the 172 run stand of Stephen Fleming and Mark Richardson posted 15 years ago.
A flurry of late wickets in the final session of the day saw Sri Lanka regain some parity of the test at University Oval.
Brendon McCullum made a quick fire 75 off 57 balls before being dismissed.
Paceman Suranga Lakmal was the pick of the Sri Lankan bowlers, taking two wickets 69 runs off 16 overs.
Guptill said "anytime you make a hundred is satisfying and to get to 150 is also pleasing and the way we were able to rotate the strike was also very pleasing and it set the tone for the day.
Guptill said it was nice to repay the faith the team and coaches have had in him "they have been good to me and given me a good run in the test side and I thank them very much for that. Today capped off a lot of hard work over the last 18 months to get back in the test side and a lot of that was with Martin Crowe over that period and today it all came together."
On day two Doug Bracewell will resume on 32 and Neil Wagner none.
