Williamson's favourite venue, and Pradeep's best

522 Kane Williamson's Test aggregate at Basin Reserve in Wellington, at an average of 65.25. It's the only ground where he has passed 500 - his next best at a ground is Seddon Park in Hamilton, where he has 242 runs in six innings. At Basin Reserve, Williamson has passed 40 in seven of his last eight innings.

66.16 Williamson's Test average against Sri Lanka - in eight innings against them he has passed 50 four times. His last six innings against Sri Lanka are: 135, 18, 54, 31*, 69, 80*.

61.14 Williamson's average in the second innings of home Tests: he has five 50-plus scores in 11 innings. In second innings of away Tests, though, his average drops to 31.90 in 21 innings.

3 The number of times Williamson has passed 50 in both innings of a Test. The two previous instances were both in 2013 - against West Indies in Hamilton, when he made 58 and 56, and against Bangladesh in Chittagong (114 and 74).

1011 Brendon McCullum's Test aggregate in 26 innings at Basin Reserve, at an average of 38.88. The only batsman who has scored more runs in Tests here is Martin Crowe: in just 17 innings he made 1123 runs at an average of 70.18.

7 The number of wickets for Nuwan Pradeep in this match, the best in his nine-Test career so far. His previous highest in a match was 5 for 112, against Pakistan in Dubai in January last year.

94 The unbroken partnership between Williamson and BJ Watling, which is New Zealand's third highest for the sixth wicket against Sri Lanka in a home Test. The highest at home is 129, by McCullum and Nathan Astle, in Napier in 2005.

311 The highest fourth-innings total at Basin Reserve, by New Zealand against England in 2008. New Zealand lost that match, though. The highest in a victory is Pakistan's 277 for 3 in 2003, when they won the Test despite conceding a first-innings lead of 170.
