Decjuba Kids is set to cross the ditch, launching in New Zealand this month.
Decjuba said the move is due to "unprecedented demand" for the childrenswear venture.
The collection will be available on Decjuba's New Zealand website from August 28.
Launched less than 12 months ago, Decjuba Kids has already rolled out 10 stores.
It is aimed at girls aged eight to 16, with best sellers including printed tees, sweats and denim.
Decjuba CEO Tania Austin confirmed the brand drops new styles weekly.
"It's now going to be easier than ever for our customers to shop the pieces they love. The countdown is on."
The new website will offer prices in New Zealand currency and ship to standard delivery times.
