The McCullum brothers starred with bat and ball to lead New Zealand to a comfortable 81-run victory over West Indies in the first T20 international in Auckland.
Brendon McCullum's unbeaten 60 was the backbone of the hosts' 189-5 and older brother Nathan followed it up by ripping through the West Indian middle order, taking 4-24.
New Zealand seized the initiative before either man had entered the fray, with Martin Guptill taking the fight to West Indies soon after Brendon McCullum had won the toss and elected to bat.
Fourteen runs off three balls during an expensive second over from Tino Best turbocharged New Zealand's early scoring rate and they made 32 off the opening three overs.
Best had his revenge when Guptill hit a long ball to short cover for 25 soon after, but that brought Brendon McCullum to the middle.
He watched a series of partners come and go - Jesse Ryder made 22 off 14 balls, Ross Taylor just five, Colin Munroe 22 while Corey Anderson was out for a duck - before Luke Ronchi arrived to form the partnership which put the game beyond the tourists.
McCullum's 60 off 45 balls featured four sixes, as did Ronchi's unbeaten 48 from 25 deliveries, with the pair seeing it through to the finish.
With a big total to defend, New Zealand rarely looked troubled during West Indies' reply.
Although Johnson Charles briefly threatened to make a game of it, scoring 11 off the opening over, fellow opener Lendl Simmons fell for a duck in the second and Charles then departed in the fifth for 16.
Nathan McCullum then took over, with the off-spinner taking the next four wickets.
Kieran Powell was the first to go for 12 in McCullum's second over, hitting a ball straight up for Guptill to snatch, and two overs later, Andre Fletcher followed for 23 - the highest scorer for the tourists.
Andre Russell followed for a duck in the same over and by the time Dwayne Bravo went for 10, West Indies were 75-6 and essentially finished.
Just to make sure, James Neesham swiftly removed Chadwick Walton and Sunil Narine to make it 77-8 for eight as West Indies limped to the finish.
