Opener Martin Guptill had a day to remember when New Zealand's home international summer began at University Oval today.
The tall Aucklander was finally dismissed shortly before stumps for 156 as New Zealand took advantage of an easy-paced pitch having been sent in by Sri Lanka.
At stumps, New Zealand, even allowing for losing their way in the final hour, were 409 for eight.
The last time they had passed 400 on the first day of a day was last Boxing Day, when they rattled up 429 for seven, also against Sri Lanka, in Christchurch.
Guptill's third test hundred, and first since 2011, was a handsome innings, laced with fine drives both through the offside and down the ground.
