Rugby World Cup Minister Murray McCully said the result capped off an already hugely successful event.
"Without a doubt, RWC 2011 will generate significant economic benefits for this country for many years to come," he said. "We welcomed 133,000 visitors to our shores and we were superb hosts for a great six-week celebration. The huge television audiences and extensive media coverage generated by the tournament boosted our international profile.
"We also forged valuable new business partnerships and showed the world we are a smart and innovative economy capable of delivering major global events.
"We made the most of being in the world's spotlight, so this result really is the icing on the cake."
New Zealand Rugby Union chairman Mike Eagle said the result was further proof of how well New Zealand had done in delivering on the promises made in Dublin in November 2005 when the NZRU won the bid to host RWC 2011.
"Few global sporting events have had to contend with so much. We were thrown the very worst of challenges - the global financial crisis coupled with the tragedy of the Canterbury earthquakes which forced us to shift seven matches less than six months from kick-off.
"Through it all our Stadium of Four Million stuck with us and turned the tournament into a really unifying experience. So to deliver it well under budget is truly amazing."
The NZRU invested $10 million in RNZ 2011 and $10 million in the redevelopment of Eden Park.
"From a rugby perspective, our investment in RWC 2011 is certainly paying off. We are seeing encouraging early signs that player registrations are up on last year and the strong gates and TV audiences we are seeing for Super Rugby are partly a spin-off from the wonderful atmosphere and exciting rugby we saw last year."
