NRL: NZ Warriors coach Andrew Webster's response to young fan's unexpected 'up the Wahs' outburst

With NZ Warriors in the midst of their best season in years, a new sporting catchphrase has swept the nation and even the youngest Kiwi sports fans have been caught up in the craze.

Move over 'Let's Gone Warriors' - in 2023 it's all about 'Up the Wahs'.

AM host William Waiirua got a first-hand taste of its far-reaching effects on Wednesday, while on location with a group of young aspiring female footballers from the 'Angry Blueberries' U8 team at North Shore club Birkenhead United AFC.

After quizzing team members Heidi, Ruby, Avalon, Charlotte, and Coco on their new Women's Football World Cup heroes, they proceeded to deliver their answers on which remaining team in the tournament is their favourite.

Following three nods for England - who'll face Australia in Wednesday's second semi-final - Coco broke script with an emphatic 'up the Wahs', much to Waiirua's bemusement.

Warriors coach Andrew Webster took a moment during Wednesday's media opportunity to take the clip in for himself, promptly exploding with laughter.

"Love it," Webster said, after "I just love where their focus is at….on the Wahs, so that's good.

"That's awesome. I'm disappointed in the three before who didn't get the right answer."

As it turns out, Coco's dad is a staunch Warriors supporter and the pair bunk down every weekend to catch their beloved side in action.

"One dad is very proud and three other dads are very disappointed."

The third-placed Warriors face Manly Sea Eagles in Auckland on Friday, where they'll be out to record a sixth straight win for the first time since 2002.
