About us History shot


Oilseed Products NZ Ltd is a family owned and operated business started by Peter McNamara in 1977. Oilseed Products was the first company in New Zealand to bring in bulk shipments of vegetable oil for the food, chemical and resin industries and bulk shipments of soyabean meal for the stock feed industry.

 The oil side of the business was initially based in an old 19th century villa on Auckland’s historic College Hill with the adjacent land housing a tank farm for the vegetable oil storage. In 1988 the tanks were sold to a bulk storage terminal on Auckland's Wynyard Wharf and were relocated from college hill to the wharf. Oilseed Products owns a 25% stake in the BST tank farm on Wynyard Wharf where the old tanks from College Hill are still in operation today. They have had a lick of paint in recent years and feature prominently in Auckland’s Wynard Quarter developments.

Sales Director, Peter Cooke joined OSP in 1993 focussing on supplying vegetable oil to local food, chemical and resin industries and trading tallow internationally. In more recent years Peter has directed the expansion of OSP NZ’s “Feeds” business supplying high quality supplements to the dairy and goat milk industries nationwide.

The poultry and stock feed side of the business was initially largely operated from our site in Auckland’s Onehunga in an old fertiliser shed that OSP purchased in 1980. 

OSP has supplied copra meal, soyabean meal and canola meal into the poultry and stock feed industries since 1980. 2007 marked the beginning of OSP’s relationship with Manildra Starches in Australia, which started the importation of Wheat DDG meal into New Zealand. This Wheat DDG was distributed to the dairy industry mainly through various feed brokers. OSP built up the market for DDG meal in New Zealand. This market has grown considerably since 2007. Farmers nationwide have seen the huge benefits of using it as a feed supplement. We have also worked hard to establish other products in the market including Hi Starch Wheat Pellets, Pasture Plus Extra pellets, a Dairy Goat Pellet and starting in 2016 a Wheat DDG Pellet for dairy cows and calves and DDG Goat pellets for goats and kids.
