AUCKLAND, New Zealand, June 19 (Xinhua) -- New Zealand's largest city Auckland was listed among the world's cities potentially at risk of over-tourism, Destination 2030 reported Wednesday.

According to the report, Auckland is a mature performer in tourism, which boasts an established tourism infrastructure, strong leisure or business travel and "good positioning to manage current growth levels," but one at risk of "future strains."

Tourism is a multi-billion-U.S. dollar business for Auckland, which accommodates more than 715,000 visitors in January 2016 alone.

Among other "mature performers" at risk were Berlin, Dublin, Las Vegas, Lisbon, London, Los Angeles, Madrid, Miami, New York, Seoul, Seville and Sydney.

The World Tourism Organization defined over-tourism as "the impact of tourism on a destination that excessively influences perceived quality of life of citizens and/or quality of visitor experiences in a negative way."

The report, Destination 2030, was carried out by the World Travel and Tourism Council and commercial real estate firm JLL.
