The McCallum’s involvement with oysters goes back to 1892, when the family came ashore at Pakihi Island, South of Waiheke. The Hauraki Gulf was their playground, where they lived off oysters, mussels, and snapper. They were always able to pick high quality oysters off the rocks. Their involvement in picking oysters and dredging mussels supported them through the Great Depression. 

Callum alongside his Father John, and two Uncles, Robbie and Bill, saw the potential for aquaculture in these clear waters of New Zealand’s Hauraki gulf. Callum had an agricultural degree and learnt more about marine farming whilst overseas. With the family owning the suitable coastal property, they had the perfect location on their doorstep for oyster farming.
