"They bring in hundreds of thousands of visitor nights every year and boost the Auckland economy," he said.
As well as the new events coming up, the city will see popular festivals - including Diwali, the Lantern Festival, the Writers' Festival, Comedy Festival, and the Pasifika Festival - return to the city once again.
Other staples include the Farmers Santa Parade, Pride Parade, Taste of Auckland, ASB Classic, Splore and New Zealand Fashion Week.
Ateed head of major events Charmaine Ngarimu said major events were recognised the world over as a way to deliver significant social and economic outcomes for cities and their populations.
"Auckland's major events celebrate our local culture and creativity, entertain our people, attract new visitors, provide unique experiences and generate economic activity," she said.
"The World Masters Games 2017 and DHL New Zealand Lions Series are the most recent examples of how events can be used to promote what is special and unique about Auckland as an attractive place for talented people to live, visit, work, study and invest.
"WMG2017 successfully showed visitors from more than 100 countries our place, our people, our hospitality and our culture, while thousands of Aucklanders took part as athletes, spectators and volunteers, and we hosted more than 34,000 international and domestic visitors for the [Lions] series, which is expected to generate $26.7 million for the Auckland economy."
Since Auckland's major events strategy was approved by Auckland Council in 2011, Ateed-sponsored major events had contributed $247m to the regional economy and 1,548,000 visitor nights (from 2011/12 FY - 2015/16 FY), Ateed said.
