The duo were announced by New Zealand's Chef de Mission Nigel Avery at a formal ceremony at New Zealand House, attended by around 250 team members.

New Zealand Olympic Committee (NZOC) President Mike Stanley was among those in attendance.

Proceedings began with a team photo and a cultural performance involving NZOC kuia Ranui Ngarimu and kaumatua Derek Lardelli.

This marks the first Commonwealth Games where New Zealand has named a male and female athlete have been able to jointly carry the country's flag at an Opening Ceremony.

Past performances, ability to lead their compatriots, competition preparation and performance standards were among the factors considered by Avery in his decision.

"These two athletes have inspired New Zealanders with their performances for more than a decade and they epitomise the special values and culture of our team," he said.

"We know they’ll do us proud as they lead our team into the Opening Ceremony, and we look forward to watching them compete over the next few weeks."

King and Walsh were presented with a pounamu pendant to wear at the Opening Ceremony, carved by Bevan Climo.

The Papatūānuku pounamu to be worn by King represents the earth mother, and Walsh's Rakinui pounamu the sky father.

King is the reigning women's singles squash champion at the Commonwealth Games.

She has also won the doubles title twice, competing with Jaclyn Hawkes on debut at Delhi 2010 and Amanda Landers-Murphy at Gold Coast 2018.

The Professional Squash Association world number five also won mixed doubles silver at Delhi 2010 and bronze four years ago, as well as singles bronze at Glasgow 2014.

The 33-year-old expressed her pride at being named flagbearer.

"I’m really honoured to be adding my name to an amazing list of Commonwealth Games flagbearers," she said.

"There's such a great team behind us so it's going to be really special to lead them onto such a big stage."

Walsh has won back-to-back men's shot put bronze medals at the Olympic Games.

He upgraded his silver from Glasgow 2014 to gold in Gold Coast four years ago at the Commonwealth Games.

The 30-year-old was world champion in 2017, but had to settle for fourth place at the World Athletics Championships in Oregon on July 17 as Ryan Crouser led an American podium sweep.

Walsh was left emotional as he stood in front of his fellow athletes.

"I’ve reflected on this a bit and I’m really proud," Walsh commented.

"It’s something that not many people get to do.

"I’m really looking forward to leading the team, waving our flag, and soaking up the whole experience."

The Birmingham 2022 Commonwealth Games Opening Ceremony is due to be held at the Alexander Stadium tomorrow.

New Zealand are due to be represented by 233 athletes.
