"I didn't think I had anything to fear," recalls Waring, who had used similar signs since last season when the shift to Eden Park was mooted.
"The response has usually been 'good on ya, mate' or 'well done'," says Waring.
The security manager told Waring he couldn't take the sign in but refused to say why.
"I stood there arguing for a while. I was bloody annoyed," said Waring. "She just kept repeating 'you can't take that in sir'. I think even somewhere like Russia would tolerate such a sign — but you have to laugh. I didn't realise a 59-year-old with a sign could be so dangerous."
Waring has followed the Warriors since their first game in 1995 and has been a season ticket holder for most of the past decade.
Eden Park sales and marketing manager Adrienne Bonell defended the actions as "a sensible decision to remove what was deemed potentially inflammatory material ... which could have prevented other patrons' enjoyment."
Warriors chief executive Wayne Scurrah he had no issue with Waring's sign. "We welcome the passion of our fans and whether they're promoting Eden Park or Mt Smart is irrelevant, the fact that they're passionate means a lot to us.
" Everyone is entitled to express their opinion."
