An unbeaten century from Brendon McCullum has guided New Zealand to 164-1 at tea on day two, leaving them 187 runs behind Pakistan with nine wickets remaining in the third and final Test in Sharjah.
Yesterday's play was suspended following the death of 25-year-old Australia batsman Phil Hughes.
Both Pakistan and New Zealand held a minute's silence for Hughes, who died of 'rare' vertebral artery dissection after his neck was struck by a bouncer bowled by Sean Abbott during a Sheffield Shield match in Sydney on Tuesday.
On the field, Pakistan, who have a 1-0 lead in the series, were bowled out for 351 before the end of the morning session.
Tom Latham and McCullum opened the batting for New Zealand and began developing a strong partnership before Latham was sent packing by Rahat Ali after hitting 13 runs.
With the Black Caps on 51-1, McCullum took control of the attack by securing the second fastest Test 50 for his nation from 30 balls and helped his side tip over the 100-run mark before the end of the afternoon session.
The 33-year-old continued to dominate the pitch by reaching a Test century off 78 balls - the quickest hundred scored by a New Zealand batsman.
McCullum (100 not out) and Kane Williamson (44 not out) will return to the crease for the evening session.
