Justin Bieber says Kiwis should keep the current national flag.
The pop idol was shown the competing flag designs during an interview with The Edge radio station today.
Bieber said New Zealand should stick with what it's got.
"Here's the thing dude, if it was up to me I'd say keep this one," he said, pointing to the familiar design.
"Are you guys not confident in your flag?"
He told the station Americans and Canadians would never change their flags.
The Canadian star was apparently unaware that Canada changed its flag to the iconic maple leaf design in 1965.
Previously, its flag - like New Zealand's - had featured a Union Jack in the top-left corner.
Bieber arrived in Auckland last night for his first visit to this country since 2013.
