Built by Samsung Heavy Industries, it is the first of six 20,000 TEU-class deliveries to Japanese shipping firm Mitsui O.S.K. Lines, and will be deployed on the Asia-Europe trade route.
Gerry Yim, managing director of Hongkong International Terminals (HIT) - which manages 16 berths at five terminals at Kwai Tsing container port - said the call of the mega vessel was an important landmark in cementing Hong Kong's long-standing position as a key global port.
The city - which was listed as the fourth busiest port in the world in 2015, has since been eclipsed by Shenzhen in terms of container traffic, with the nearby ports of Guangzhou and Xiamen catching up quickly.
To accommodate larger vessels, the government undertook a dredging exercise to deepen the Kwai Tsing container basin and its approach channel.
The NZ$90 million project, which began in 2013, was completed last year.
Transport minister Anthony Cheung Bing-leung said: "Mega vessels are becoming a container shipping trend. Our newly dredged approach channel with a navigation depth of 17 metres can accommodate mega vessels in all tides. We look forward to receiving more of such vessels in the future.
"With its strategic location, free port status, world-class infrastructure and world-renowned efficiency, Hong Kong is one of the most popular ports in the world."
After a 14-hour stop, the vessel set off for the port of Yantian in neighbouring Shenzhen at 5pm the same afternoon, before continuing to Singapore, the United Kingdom, Germany and France.
Its status as the world's largest container ship in service seems to be short-lived however, as the 20,568-TEU Madrid Maersk was delivered on April 11 and is expected to be in operation soon.
