Our history dates back 50 years, when we started creating truly authentic flavours

An innovative approach to classical French recipes

Many great dishes are finished with a flourish of sauce and our story begins with one – authentic, delicious mayonnaise.

At a time when New Zealanders had little idea of what true mayonnaise was and how it tasted, Chef Maarten Groen arrived from the Netherlands and drew on his European heritage to create a mayonnaise he was sure would appeal to the tastes of the Pacific.

Over the following 40 years, we’ve stayed close to our food heritage while managing to
add a wide range of other sauces, dressings and condiments as tastes and trends evolved.


In 2018 we became a part of Golden State Foods (GSF), one of the largest diversified suppliers and manufacturers to the foodservice industry. Partnering with a global organisation allows us to create a worldwide network to exchange knowledge and trends and deliver insightful food solutions to our customers.

Our strong values are the backbone of our organisation. We believe in producing the best products, with the highest quality standards, with the power of people; we pride ourselves on building strong and fair partnerships with leading local and global foodservice customers.

With multi-packaging capability, Groenz provides shelf stable products in several pack formats and sizes to support our customers' needs in food preparation. 

In addition to our brands - Frenchmaid, Kiwi Style and In House Systems – we have a strong focus on custom-made solutions, including but not limited to: custom made recipes, product ideation, menu innovation and more.
