Blackcaps opener Devon Conway has become the seventh man to score a double century on test debut, as New Zealand finished day two of the first test against England with a lead of 267 at Lord's.
Conway, 29, began the day with 136 runs to his name, thanks to his unbeaten effort on day one, alongside Henry Nicholls, who had 46.
Nicholls was the first to reach his milestone on day two, reaching a measured half-century from 158 balls, before Conway got to 150 - raising his bat again - taking 258 balls.
But once Nicholls fell for 61, caught by Ollie Robinson off the bowling of Mark Wood, New Zealand's middle order collapsed.
From 288/3, the Blackcaps slipped to 338/9, as the middle and lower order of BJ Watling (1), Colin de Grandhomme (0), Mitchell Santner (0), Kyle Jamieson (9) and Tim Southee (8) all failed to reach double figures.
In search of more runs, Conway found a valuable ally in Neil Wagner, who made a valuable 25 from 21 balls batting at No.11, including a huge six off the bowling of Stuart Broad.
Running out of partners, Conway upped the ante, before hooking Wood over fine leg for six runs, and in doing so joined the club of batsmen to score a double century on test debut.
Conway's 200 came from 347 balls, with 22 fours and one six.
Attempting to farm the strike, Conway's innings was finally ended through a run out, failing to make his ground as England captain Joe Root removed the bails to see the left-hander short of his ground and out for exactly 200 - as New Zealand were bowled out for 378.
Only Mathew Sinclair (214) has made a higher score for New Zealand on test debut than Conway's 200.
Ollie Robinson was the pick of England's bowlers, taking 4/75 from 28 overs on his test and international debut.
With ball in hand, the Blackcaps got off to the perfect start, as Kyle Jamieson trapped England opener Dom Sibley LBW for a duck, before Tim Southee removed Zak Crawley - caught behind by Watling for two.
Precariously poised at 18/2, England recovered and got through to stumps, thanks to an unbroken partnership of 93 between Rory Burns (59 not out) and Root (42 not out).
The two sides will resume tonight, with three days' play still to come in the first test.
