Josh Little becomes just the sixth man to take a hat-trick in a T20 World Cup by the way.
He joins Brett Lee, Curtis Campher, Kagiso Rabada, Wanindu Hasaranga, and Karthik Meiyappan.
Ireland are now the only nation to have two players on that list too.

New Zealand have been really impressive throughout this tournament.
Ireland are going to let Josh Little walk off first, a hat-trick at a World Cup - how good? This is going to be too many for Ireland to chase, though.

It's been a good recovery at the end of the innings from the Ireland bowlers.
BreakingIreland need 186 to win
A decent final over from Mark Adair - there are no boundaries, which is always a success at this stage. Ireland have fought back nicely in the last two overs.
What a lovely thing to conclude Ireland's memorable World Cup campaign.
NZ 176-6
A standing ovation for Josh Little at the end of the over. He deserves it.
What a few months he is having. He got a late call-up to The Hundred and took the best ever figures in the competition and now he's got a World Cup hat-trick.
Go on lad.

It's a great delivery from Josh Little. That is more out than the ball before! Josh Little has got himself a World Cup hat-trick.

Santner lbw b Little 0 (NZ 174-6)
BOOM! HAT-TRICK FOR JOSH LITTLE!
It is so, so out. It's crashing into middle stump again.
Superb bowling from Little. He's definitely going to be getting deals in franchise leagues around the world. His reputation is really growing.

Mitchell Santner wants to review it. It's more in hope I think...

That was quick ball from Little, 88mph. The only thing that will save Neesham is if there is bat involved.

Two in two!
Josh Little has Jimmy Neesham pinned in front.
The Kiwi almost reluctantly reviews.
