Kane Williamson became the second New Zealand batsman to score 1000 Test runs in a calendar year as the hosts built an imposing 308-run lead over Sri Lanka heading into day four of the first Test in Dunedin.
Williamson, who achieved the milestone when he surpassed eight runs, was 48 not out at the close of play, with Tom Latham on 72, as New Zealand ended day three at a chilly and windswept University Oval on 171 for one.
Martin Guptill, on 46, was the only batsman to be dismissed in the hosts' second innings when a delivery from left-arm spinner Rangana Herath barely bounced, scuttled along the wicket and clattered into his stumps.
That delivery gave pace bowler Tim Southee some hope the pitch could help his side try to dismiss Sri Lanka in the fourth innings, especially since it took 117 overs to bowl them out for 294 in their first knock.
"There were signs of a couple that stayed low and that's encouraging considering it's only day three," said Southee.
"It's definitely not going to come easily... Patience and delivering the ball in tight areas is one of our strengths as a bowling unit. It's going to be challenging, the new ball will be crucial."
Guptill, who scored 156 in the first innings, fell after a 79-run opening partnership with Latham, having given New Zealand a perfect start to build on their 137-run first innings lead, with an eye to setting Sri Lanka a target in excess off 400.
Williamson, who started on 992 runs this year, used his feet to hit Herath down to the long on fence to move from seven and achieve the milestone.
Captain Brendon McCullum was the first New Zealand batsman to achieve the mark, in 2014.
Latham, who had a series of starts without kicking onto a big score in the recently completed series against Australia, scored his seventh test half century as he and Guptill were cautious before tea then accelerated the run rate afterwards.
Rain has been forecast for Dunedin for the fourth day.
The visitors had begun the day on 197 for four and, while they lost two quick wickets in the first session, Milinda Siriwardana, with 35, and Herath, with 15, guided Sri Lanka past the follow-on target and then frustrated New Zealand's bowlers with the way they were able to occupy the crease.
