Gull was established in 1998 and is New Zealand’s largest independent vertically integrated fuel retailer and terminal operator. Gull operates a network of 117 retail outlets, the majority of which are unmanned sites, and retails over 500 megalitres of fuel annually.

It is also the only independent operator which has vertically integrated fuel supply capability, owning a strategic import terminal located at Mount Maunganui.

Allegro acquired the business in July 2022 from Ampol.
