The country's brand as a safe, postcard-pretty and accessible destination - after the daylong flight that is - means lots of visitors knocking on our door.
The boom has caught the country by surprise, created growing pains, and reinforced the need for the industry to work together.
In Queenstown, many of those with hospitality jobs have moderate incomes but pay high rents. In Tongariro National Park, the queue of hikers tempted by alpine walks threatens to spoil the experience.
In Otago, locals complain of the driving habits of visitors. The Department of Conservation's Great Walks draw visitors by the busload but lose money by the truckload as expenses outstrip income. These, by and large, are niggles which can be addressed without massive investment but they should not be allowed to fester.
Surveys of tourism perceptions have found that the number of New Zealanders who believe tourism is putting too much pressure on the country continues to grow.
The Conservation Act is 30 years old and would benefit from an overhaul. Self-drive rental vehicles and campervans for instance can avoid the fees DoC charges visitors to its estate.
Despite the rising value of nature as an alternative to medieval cities and ancient monuments, the country's priceless outdoor assets must seem like bargains to overseas visitors who access them for the same price as the holidaying New Zealand family.
If that same family finds the queues getting too long, existing niggles could become noisome.
New Zealanders know that tourism is now a foundation of the economy. But surveys of tourism perceptions have found that the number of New Zealanders who believe tourism is putting too much pressure on the country continues to grow.
While still in the minority, more and more of us think we get too many tourists, and many blame the industry for strains on infrastructure and traffic congestion.
Tourism Minister Paula Bennett, while concerned some are getting "a bit whingey" about the industry, is expected to announce extra spending in this month's Budget to address pressure points.
The funds need to help protect the golden age of travel, and the benefits it delivers New Zealand, from becoming tarnished.
