MOUNT MAUNGANUI: New Zealand`s ruthless pace attack carved up Pakistan to deliver a crushing 115-run win in the fourth Twenty20 on Sunday and clinch the five-match series.

The home side moved 3-1 ahead after defending 220-6 in Mount Maunganui and then dismissing a ragged Pakistan for just 105 in the 17th over.

Jacob Duffy claimed 4-20 and fellow seamer Zak Foulkes 3-25 as Pakistan suffered their biggest T20 loss by runs against all nations, eclipsing a 95-run defeat against New Zealand in Wellington nine years ago.

The tourists were reduced to 9-3 after two overs with Duffy bagging two scalps in his first over, both caught by wicketkeeper Mitch Hay.

Duffy`s first victim was Hasan Nawaz for one, two days after thePakistan opener blasted a maiden century in game three in Auckland to keep the series alive.

Teetering at 56-8, Pakistan`s innings had some credibility restored thanks to 44 off 30 balls from all-rounder Abdul Samad.

The only other batsman to score in double figures was Irfan Khan with 24.

Pakistan captain Salman Ali Agha said New Zealand`s bowlers exploited some helpful conditions under lights.

`They bowled really well and they outplayed us,` Salman said.

`I mean, the ball talked. It was swinging and it was turning as well. But we are international cricketers, so we have to adapt that and we have to be better.

`We need to regroup and we need to win the last game.It was New Zealand`s second biggest T20 win by runs, nearly surpassing their 119-run drubbing of the West Indies in 2018 at the same Bay Oval venue.

Earlier, Finn Allen raced to 50 off just 20 balls, putting on 59 for New Zealand`s opening stand with Tim Seifert, whose 44 took 22 deliveries.

Seifert was the first of three batsmen dismissed by seamer Haris Rauf, who claimed 3-27.

Allen struck six fours and three sixes while captain Michael Bracewell was nearly as effective at the death, blasting 46 not out off 26 balls.Bracewell was delighted with his team`s all-round response to the loss at Auckland.

`Bouncing back only a day or so after the performance at Eden Park was outstanding,` he said.

`It shows the benefit of those guys batting so well at the top, they got us well ahead of the game.

`All the seamers bowled brilliantly tonight. It`s nice when you give bowlers a go, like Zak Foulkes coming into the match.

Three wickets for him was a brilliant performance.

Game five is in Wellington on Wednesday.-AFP
