Auckland mayor Phil Goff had been pleased the festival could still go ahead this year.
"Pasifika is a much-loved festival and an important celebration of Auckland's vibrant Pacific cultures," he said.
"I'm happy that Auckland Unlimited, our Pacific community leaders, organisers and festival stakeholders have been able to work together to confirm a new date.
"I look forward to attending Pasifika this year and enjoying all the performances, music, art, culture and heritage the festival offers."
Head of major events at Auckland Unlimited, the city's economic and cultural development agency, Richard Clarke said the festival could only proceed at alert level 1.
"Even though the Prime Minister indicated yesterday that Auckland may move to alert level 1 next weekend, this is not guaranteed," he said.
"We haven't been able to hold Pasifika since 2018, so moving the event dates will give us the best chance of Auckland being able to enjoy another fantastic festival.
"We are grateful for the support of the community leaders and event partners who have worked with us in the past week to explore all options since Auckland moved to alert level 3.
"They support our decision to postpone and will be working with our experienced event production team on the new plans to deliver the festival at a later date."
