Murray was a little lost for words when he heard his name read out by Henare in the team meeting on Sunday.
"I am so grateful for the opportunity that lays before me," Murray said. "It has been amazing learning from some of the finest players and coaches that New Zealand has to offer during the course of the camp, and I am just so excited for the next few weeks."
Murray will have plenty of veterans around him in the squad, with Tall Blacks stalwarts Tom Abercrombie, Corey Webster, Alex Pledger and Rob Loe all named in the squad.
"Being in the Tall Blacks environment is always energising," Abercrombie said. "I love being a part of this team and there is an added edge for a World Cup campaign, we have seen and felt that already these past few days.
"I am excited to be a part of a team that can't wait to roll up our sleeves and in typical Tall Blacks fashion take on the world and look to upset the odds along the way."
