Auckland will spend $2.7 million on its opening night celebrations for 50,000 people and the international media.
The money comes out of a $35 million council budget for Rugby World Cup operating expenses, and $100 million overall cost including infrastructure upgrades.
The Herald yesterday revealed how the celebrations will span the waterfront from the Viaduct Harbour to Queens Wharf on September 9, featuring Dave Dobbyn, the Finn Brothers and a huge fireworks display.
Mayor Len Brown said they were a way of saying thank you to Auckland for its investment in the tournament.
"It's a once-in-a-lifetime extraordinary spectacle, and it's an extraordinary opportunity to portray the natural beauty and the excitement of this place," Mr Brown said.
