The tradition in ice hockey world championships is for the winning team's national anthem to be played at the end of the game while both teams stand in a line on the ice.
New Zealand won the third division world championships when it thumped Ireland 9-0 in front of 1500 fans.
"It was what we came here to do. I am proud of the boys," head coach Jeff Bonazzo said.
"It was a good team effort. We were a bit undisciplined tonight but we still managed to come through.
"We are getting better every year and I'm confident we can do well in the second division next year."
A feature of the Ice Blacks' play during the championships has been their fitness and aggression.
They needed this in the first period when Ireland came out aggressively and took the game to the Ice Blacks in a bruising encounter when both sides were thumping opponents off the puck and into the backboard.
But Ireland suffered the most and were penalised frequently to give the advantage to the Ice Blacks.
Irish forward Adam McCaul came off second best when he attempted to bash into the Ice Blacks and spent time in the sin bin.
The best player for the Ice Blacks in the game was goal tender Rick Parry who displayed vision in his defence and occasionally acted as the third defender.
He was named New Zealand's most valuable player.
Brett Speirs (26), of Queenstown, made three telling runs up the centre and finished the championships with five goals.
The talented Mark Morrison showed attacking skills for Ireland.
The only goal of the first spell came from a power play when Canterbury's Dale Harrop netted after 11 minutes.
He was assisted by Josh Hay and KC Ball.
The Ice Blacks took the game out of Ireland's grasp by scoring three quick goals in the first four minutes of the second period to take an unassailable 4-0 lead.
The scorers in quick succession were Stacey Rout, Braden Lee and KC Ball.
The Ice Blacks turned up the heat in the third period to add five more goals and take complete control of the game.
Two goals were scored by Chris Eaden to take his tally for the championships to five, while Braden Lee completed a hat trick in the game.
New Zealand was the only unbeaten team at the championships and won the world third division title with 14 points.
It was followed by Turkey 12, Luxembourg 9, Greece 7 and Ireland 3.
New Zealand and Turkey will both be promoted to second division of the world championships next year.
Earlier, Turkey went on a goal-scoring spree in the third period to beat Greece 7-1.
New Zealand 9 (Dale Harrop, Stacey Rout, Braden Lee (3), Chris Eaden (2), Brett Speirs, and KC Ball), Ireland 0.
Turkey 7 (Yavuz Karakoc 3, Serkan Yapicilar 2, Emrah Ozmen, Serkan Gumus), Greece 1 (Georgios Kalyvas).
