Brough, who should become Scotland’s most-capped player during the tournament, is excited by the tournament.
The Huddersfield halfback said he always planned to make himself available for the Bravehearts.
“When Steve asked me if I was available I said yes straight away,” he said.
“There wasn’t a decision to make as far as I’m concerned. We’ve had a bit of success and I’ve really enjoyed playing for Scotland.
“The people involved – the players, the coaches and the staff – have been there a long time and I love being a part of it. It’s going to be a massive challenge.
“Last time we played New Zealand they tore us apart second half, but I’m looking forward to it.”
Scotland head coach Steve McCormack gave Brough his debut in his very first match as Bravehearts boss way back in 2004, when Brough was a young halfback who had just signed for Hull FC from York City Knights.
Brough will draw level with record appearance-maker Andrew Henderson when he plays his next – and 21st – international.
“It’s great news that Danny has confirmed he will be with us again this year,” McCormack said.
“We met up last week and had a long chat about how we see the side playing and what we are going to do to meet what is clearly a massive challenge.
“But having a world-class player like Danny leading the team again is an inspiration to others. He’s the heartbeat of the team.”
“If I break the record as most-capped player that will be really special,” Brough said.
“It would be a great achievement. I intend winning many more so not many others can overtake me!
“The body’s alright: I feel good. We’ve got the World Cup next year too so, injury permitting, I hope to set a record that will be tough to break.”
