Jimmy Neesham and Colin de Grandhomme came to unbeaten New Zealand's rescue with a 132-run partnership to lift the 2015 World Cup finalist's total to 237-6 against Pakistan.
Left-arm seamer Shaheen Afridi (3-28) had helped reduce the Black Caps to 46-4 and 83-5, when Kane Williamson was out for 41.
Neesham finished on his highest ODI score, 97 not out from 112 balls. He hit five fours and three sixes, including smashing a six off the last ball of the innings.

De Grandhomme was run out, too slow against Mohammad Amir's throw while going for a second run, to finish on a 71-ball 64.
New Zealand narrowly chased down South Africa's 241-6 on the same Edgbaston wicket and this score, while it appears to be a sub-par total, could prove a nervy pursuit for seventh-place Pakistan in a must-win game.

If New Zealand win they will join title holders Australia in the semi-finals.
"The cloud is going to hang about a bit and it's cold. There might be a bit of swing but we'll have a bat," said Williamson.
"There was consideration to making some changes but we've kept it the same again. This is always a tough game. Pakistan are a very strong side but we are looking to build on our displays.
"Naturally the support that Pakistan have gives a great atmosphere, we are looking forward to it. Every game has similar feelings riding on it -- we are looking to play the Cricket we want."
Pakistan captain Sarfaraz Ahmed said he would also have chosen to bat first.
"Mohammad Amir is bowling very well. We put in a complete team performance last time but our catching is a concern. Pakistan can do anything, we go match by match."

It was a superb display by the underdog Black Caps, who came into the match on the back of three straight defeats by Pakistan, Australia and England and only qualified for the semi-finals on net run-rate, while India topped the 10-team group stage.
Paceman Tim Southee missed out due to a calf injury as the Kiwis -- runners-up in the 2015 edition -- went in with two all-rounders in their starting line-up.
It is the first time England have reached this stage since 1992, when they made the last of their three losing appearances in the final.
Victories from Lakshya Sen, the doubles pair of Satwiksairaj Rankireddy-Chirag Shetty and former World No 1 Kidambi Srikanth guided India to the coveted trophy, the most prestigious title in men's team badminton.
Liverpool star Mohamed Salah invited his compatriot Moamen Zakaria to attend the match, as he is currently in Britain for treatment of a rare disease, amyotrophic lateral sclerosis.
Police said the accident took place at Hervey Range, west of Townsville on Queensland's east coast.
