REUTERS: Devon Conway and Will Young scored half-centuries as New Zealand finished the second day on 229-3, 74 runs behind England's first innings score in the second and final Test against at Edgbaston on Friday.
Left-handed batsman Conway, fresh from his brilliant double hundred on debut at Lord's in the opening test, smashed 12 boundaries for his 80 and alongside Young added 122 runs for the second wicket.
Young showed incredible patience for his 82 off 204 balls before he became Dan Lawrence's maiden test wicket in the final over of the day. The tourists finished the day with Ross Taylor unbeaten on 46 at the other end.
New Zealand's stand-in skipper Tom Latham was trapped leg before with just 15 runs on the board before Conway and Will Young went on to frustrate the English bowling attack.
Conway was spared on 22 when the South African-born batsman edged seamer Stuart Broad to Zak Crawley in the slips.
But with on-field umpire Richard Kettleborough having made a soft signal of not out, TV umpire Michael Gough decided there was insufficient evidence for him to overturn that decision.
Young, who replaced injured skipper Kane Williamson in the top order, should have been certainly out for seven but England captain Joe Root dropped a seemingly comfortable chance at first slip despite getting both hands to the ball.
Conway missed out on another triple-figure score when he holed out to Broad in the final session, but Young continued to show great maturity at the other end.
Young, playing only his third test, built a 92-run partnership with Taylor as England struggled to make an impact without a full-time spinner in their lineup.
Earlier, tailender Mark Wood's flashy 41 helped England to 303 all out in their first innings, with Mark Lawrence finishing unbeaten on 81.
Wood, who resumed on 16 not out, scored six boundaries before edging a Matt Henry delivery back onto his stumps.
On his return to action, Trent Boult was the pick of the bowlers for the tourists as he trapped James Anderson leg before to finish with 4-85.
