Kookai has partnered with Fiji Water in support of the label's own charity The Katalyst Foundation.
Fiji Water is now stocked in all 36 Kookai boutiques across the country.
The bottles are available in stores for a $2 donation, with all funds going directly to the Katalyst Foundation providing long-term sustainable solutions to poverty in underdeveloped countries.
Kookai MD Robert Cromb said the cause is close to home.
“Having been born and raised in Fiji myself, it’s incredibly fulfilling for Kookai and our customers to have an opportunity to support the Fijian community through a Fijian product.”
The retail partnership is an extension of the long-standing relationship between the two brands.
For the past two years, FIJI Water has supported Kookai's fashion shows and season launches around Australia.
This is similar to its global fashion partnerships alongside brands such as Rodarte and Altuzarra.
