New Zealand slumped to two for two, before escalating at 4.92 runs an over to reach tea on 123 for three in a circus act of test cricket against England at Headingley.
After the initial shudder, Tom Latham anchored the innings with his seventh score of more than 50 in 20 innings, milking 51 runs off 86 balls after almost two hours at the crease.
The session's most entertaining element came with captain Brendon McCullum's arrival after Latham and Ross Taylor (20) delivered a 66-run resistance for the third wicket.
In what shaped as a personal vendetta after a golden duck in his second innings at Lord's and subsequent criticism of his team's aggressive approach, McCullum banished his first ball from Stuart Broad for six over cover. 'Bonkers' they might say in these parts... but with the utmost admiration. The Headingley crowd, often considered a tough gig, whooped in appreciation. McCullum bristled with intent, his fast-twitch fibres were on parade and he raced to 41 off 27 balls in a compelling three-quarters of an hour.
It wasn't always so rosy.
Martin Guptill became James Anderson's 400th test wicket in the third over.
