New Zealand welcomed tourists from the US, Canada, Britain, Japan, and more than 50 other countries for the first time in more than two years Monday after dropping most of its remaining pandemic border restrictions.

The country has long been renowned for its breathtaking scenery and adventure tourism offerings such as bungy jumping and skiing. Before the spread of COVID-19, more than 3 million tourists visited each year, accounting for 20 percent of New Zealand's foreign income and more than 5 percent of the overall economy.

But international tourism stopped altogether in early 2020 after New Zealand imposed some of the world's toughest border restrictions.

The border rules remained in place as the government at first pursued an elimination strategy and then tried to tightly control the spread of the virus. The spread of omicron and vaccinations of more than 80 percent of New Zealand's 5 million population prompted the gradual easing of restrictions.

New Zealand reopened to tourists from Australia three weeks ago and on Monday to about 60 visa-waiver countries, including much of Europe. Most tourists from India, China, and other non-waiver countries are still not allowed to enter.

Tourists will need to be vaccinated and test themselves for the virus after arriving.

"Today is a day to celebrate, and is a big moment in our reconnection with the world," said Tourism Minister Stuart Nash. At Auckland Airport, flights bringing in tourists began landing from early in the morning, coming in direct from places including Los Angeles, San Francisco, Kuala Lumpur, and Singapore.

The border reopening will help boost tourism ahead of New Zealand's upcoming ski season. But the real test of how much the tourism industry rebounds will come in December when the peak summer season begins in the Southern Hemisphere nation.
