NZ's first-day highs, and Guptill's long wait

2 Number of instances of New Zealand making 400 or more on the opening day of a Test, before their 409 for 8 today. They scored 452 for 9 against Zimbabwe in Harare in 2005-06 and 429 for 7 against Sri Lanka in Christchurch in 2014-15. Also the run rate of 4.54 the end of the day is their fifth-highest in the first innings of a Test.

40 Consecutive Test innings Martin Guptill went without a century, before his knock today. His last hundred was 109 against Zimbabwe in Bulawayo in 2011-12. Between these two centuries, he made eight fifties with a best of 97 against West Indies in North Sound in 2012. In the same period he made seven hundreds in 64 ODI innings.

1997 The last time a New Zealand opener made 150 or more in the first innings of a Test, before Guptill's 156 in this match. Bryan Young scored 267 not out against the same opposition in the same city, but at a different ground, Carisbrook. Overall, it is the fifth instance for New Zealand, and all have been against Asian teams - three against India and two against Sri Lanka.

5 Number of New Zealand players who have taken more innings to reach 2000 Test runs than Guptill's 70 - Daniel Vettori (96), Richard Hadlee (91), Adam Parore (83), Ken Rutherford (79) and Chris Cairns (73). Guptill became the 26th New Zealand player to reach this milestone and the joint sixth-slowest with John R Reid. His average of 30.37 is the fifth-lowest among all the New Zealand players with 2000 or more runs.

173 The partnership between Kane Williamson and Guptill, New Zealand's highest for the second wicket against Sri Lanka in Tests. It bettered the one between Stephen Fleming and Mark Richardson at the P Sara Oval in Colombo in 2003-04 by one run.

13 Number of scores of 85 or more for Williamson in international matches this year, which is the joint-most by a batsman in a calendar year with Aravinda de Silva (1997), Sachin Tendulkar (1998), Tillakaratne Dilshan (2009) and Hashim Amla (2010). It was Williamson's 19th score of 50 or more in international matches this year in 42 innings, the second-most behind Joe Root who has 20 such scores in 45 innings. Williamson is already the leading run-getter in international matches this year.

15 Consecutive Tests in New Zealand in which the team winning the toss opted to field first, including Sri Lanka in this Test. The last time any team batted first here was New Zealand against Pakistan in Wellington in 2010-11.

98 Tests played by Brendon McCullum, without missing any since his debut. He equals AB de Villiers' record of playing the most consecutive Tests from debut.

19 Number of sixes hit by McCullum in Tests against Sri Lanka, the most by a batsman against them, bettering Navjot Sidhu's 18 sixes. Sri Lanka is also the opposition against whom McCullum has hit the most sixes: he has 18 against England. His Test strike rate of 78.67 against Sri Lanka is the second-highest among all batsmen who have faced 500 or more balls against them.
