Karachi (Web Desk/Agencies): New Zealand set 262-run target for Pakistan in the second one-day international (ODI) in Karachi.
Nawaz finished with 4-38 as New Zealand slumped from a strong 183 for one in 29.5 overs to 206-6, losing five wickets for 23 runs in the space of 40 deliveries.
New Zealand won the toss and decided to bat first and they were lifted by a second-wicket stand of 181 between Conway (101) and Kane Williamson (85) before they slumped to the spin of Nawaz.
Fast-bowler Naseem Shah (3-58) broke the stand when he dismissed Conway off the last ball of the 30th over.
Conway hit 13 boundaries and a six off 92 balls, his second hundred in one-day internationals.
His stand with Williamson is a record against Pakistan, beating the 159 set in Wellington by Williamson and Martin Guptill in 2016.
Nawaz then initiated destruction, dismissing Daryl Mitchell (five) and Tom Latham (two) in one over before clean-bowling Williamson in his next.
Williamson, dropped on 53 and 54 off Mohammad Wasim, cracked 10 boundaries from 100 balls.
Glenn Phillips scored three and Michael Bracewell eight, while Mitchell Santner was the last man out for 37.
On Monday, Pakistan defeated New Zealand by six wickets in the first ODI of three-match series.
The third and final ODI will also be played in Karachi on Friday.
