Joining Styles on the tour is UK pop singer Mabel.
The tour announcement for the New Zealand and Australian shows had been teased on social media earlier this week.
Australia and New Zealand promoter Live Nation shared Tweet, posting a link to website tasteslikestrawberries.com, which is coincidentally the first lyric of the former One Direction member's song Watermelon Sugar.
The post also has a white circle with a hand, which is similar to Styles' album artwork along with the white font used.
Styles last played a show in New Zealand in 2018.
As well as the New Zealand date, he's playing shows in Sydney, Brisbane, Melbourne, and Perth.
Harry Styles performs at Auckland's Spark Arena on Monday, November 23, and tickets go on sale next Friday.
