All Black fans ducked and screamed in terror as they were struck by stray fireworks during a pre-match pyrotechnics display at Eden Park last night.
NZRU chief executive Steve Tew pledged to investigate after one spectator wound up in hospital with serious head injuries and two others were wounded by the misdirected missiles.
A spectator described the scene of panic as the deafening boom from the fireworks caused parts of the 48,000-strong crowd to duck below their seats. They were then hit by what felt like shot-gun pellets, she said.
"When those explosions went off after the haka they gave us a hell of a fright. We all ducked. They were so loud. Then immediately afterwards people in front started screaming and crying out as the injured ones got out of their seats and shocked people were looking round trying to see where all the blood had come from."
