But she didn't mention that Little, who won awards for his production work on Lorde's debut Pure Heroine, had anything to do with the song.
Lorde's record label Universal Music confirmed Little's involvement to the Herald.
And in a tweet posted shortly after Green Light's release, Little said he was "really proud" to be part of the song's creation.
Little also retweeted a Lorde fan account that posted a screenshot of the song's APRA listing, which credits Little, Jack Antonoff and Lorde as writers.
Green Light was produced by Antonoff and Lorde herself, with additional production from esteemed hip-hop producer Frank Dukes.
Antonoff tweeted thanks to Little, Dukes and his engineer Laura Sisk on Friday.
Little told the Herald in 2016 he'd held writing sessions with Lorde for the follow-up to Pure Heroine, but said he was no longer working on it. He said she was "trying to do something different (and) working with other producers is a part of that".
Lorde told ZM's Fletch, Vaughan and Megan she made a conscious effort to move beyond the sound of Pure Heroine.
"When I first started writing for a new project I was writing a lot of stuff that sounded like Pure Heroine, and I think that happens to all artists. You need to get the last record out of you before you make anything new," she said.
