Last month a 27-centre RWC 2011 Roadshow was promoted as taking the William Webb Ellis Cup to the country, and promoters said more than 11,000 New Zealanders had their photo taken with it.
However, TV3 reported last night that the 'real' cup was getting minor repairs in Ireland and competition organisers didn't make the distinction between it and the replica public, for security reasons.
Rugby World Cup Ltd, the subsidiary of the International Rugby Board, which owns the Tournament, said it possessed two cups.
"As is common with other major sports tournaments, we have two trophies, however only one is ever used at any given point in time," said Tournament director Kit McConnell.
"Both cups are equal in stature. There is no original cup as such, they are interchangeable and we don't distinguish between the two. They were both acquired before the first Tournament so share the same Rugby World Cup history.
"Both have been used at past Tournaments and both have been in the hands of winning captains and teams. They both represent the spirit of the Game.
"I want to reassure New Zealand fans that the Cup they have enjoyed recently on the RWC 2011 Roadshow will be the one held aloft on October 23 by the winning captain."
Rugby commentator Keith Quinn says he'd always known there were two Cups in existence, the older one made in Britain which is the one that is always presented at the end of the tournament and is more valuable.
It didn't bother him that there was a back up.
"If it looks like the Rugby World Cup and feels like the Rugby World Cup - it's the Rugby World Cup," he said.
