In September, activity and attraction numbers dropped 1.7 per cent overall, which Bui said reflected the narrow focus and tight schedules of Cup visitors.
Many had not researched destinations before travelling and Bui said, even if they arrived in Rotorua and were impressed by how much there was to do, they probably needed to leave within 24 hours to get to their next destination and game.
Rotorua Holiday Accommodation Parks Association of New Zealand spokesman David Adams, of the Rotorua Top 10 Holiday Park, said the tournament had been very good for his industry through September and October.
"I think that had quite a bit to do with the marketing by the campervan companies."
Adams said the convenience of combining accommodation and transport appealed to a lot of people who were travelling around the country and did not want to be constantly packing and unpacking at each stop.
Airport marketing manager Rhys Arrowsmith described the Cup as fantastic, with inbound and outbound international passenger numbers climbing throughout the tournament.
"We have also seen a steady increase in Australian residents making up the numbers. World Cup fans in their team shirts made it very easy to identify who and why they were here."
