Hundreds of officials, politicians, business and trade representatives are gathered at the Viaduct Events Centre in Auckland today for the second Tripartite Economic Summit.
That joins Auckland with Los Angeles and Guangzhou.
Los Angeles mayor Eric Garcetti told delegates Auckland and LA were united by the Pacific and said people had arrived here hoping to find prosperity.
LA representatives here for the summit come from Universal Studios Hollywood, American Airlines, the Los Angeles Tourism and Convention Board, the LA's mayoral office, the United States Department of Commerce, the Los Angeles Business Council and a big delegation from Los Angeles World Airports.
Auckland mayor Len Brown said Auckland was growing and all three cities faced the same challenges. The biggest growth in new visitor arrivals to Auckland and New Zealand was coming from China, Brown said, describing Garcetti as being more like a rock star.
