Hotel room prices are likely to rise by up to four times at the peak of the Rugby World Cup in October next year.
Industry research says that is in line with previous tournaments overseas and hoteliers say it will not damage the country's tourism reputation.
The six-week tournament could draw an estimated 85,000 overseas visitors.
Major hotels have yet to list their prices for the event, but property consultant Jones Lang LaSalle says prices could double for the pool matches and as much as quadruple for the knockout rounds.
The Hotel Council, which represents major providers, says while New Zealand has not previously hosted such a large event, many hotel managers have had similar experience overseas.
Council chair Jennie Langley says hoteliers understand the balance between raising prices and the long term importance of the event to tourism.
