Petrol and other fuels were originally shipped in drums and tins but as the demand for petrol increased in the 1920's and 1930's oil companies began to develop bulk fuel distribution systems for their products. Petrol, Kerosene and other petroleum based products were imported into New Zealand by ship and stored in large fuel storage tanks at the major ports. It was then transported to smaller fuel depots around the country by coastal shipping, road or by rail. The fuel was then distributed to local outlets by truck.
Like many other service towns in New Zealand, Oamaru had a number of small fuel depots. Three fuels depots were located at Friendly Bay in Oamaru Harbour. Operated by The Shell Company of New Zealand Ltd, Vacuum Oil Coy Pty Ltd (Mobil) and Caltex Oil N.Z. Ltd these depots were used to store and distribute fuel, oils and other petroleum based products across the Waitaki.

For the first few decades fuel and petroleum products were transported to the fuel depots by rail before being distributed by road.
In 1953 Shell New Zealand completed construction of the large bulk fuel tanks at their depot and in December of that year their coastal oil tanker M.S. Tanea began calling at Oamaru Harbour. Fuel and petroleum products were unloaded at Holmes Wharf and transferred by pipeline to their tanks.
M.S. Tanea was a regular visitor over its eleven years of service with Shell in New Zealand. With the opening of Marsden Point oil refinery in 1964, new oil tankers were introduced on New Zealand's shipping routes. Unfortunately these new tankers were too large for Oamaru Harbour. M.S. Tanea continued calling at Oamaru until 1965 when Holmes Wharf was upgraded and the pipeline used to transfer fuel from the wharf to the Shell depot was removed.
For fuel transported by rail the fuel depots were served by a single dead end private siding that was located between the western boundary of the fuel depots and Oamaru goods yard. The siding was accessed from a set of points at the south end of the goods siding.

Each of the fuel depots consisted of a variety of tanks and buildings for the storage of fuel and other petroleum products in bulk and in barrels and tins.
An excursion train hauled by a small steam shunter D16 from the Waitaki Farmers Freezing Works at Pukeuri passes the fuel siding at the goods yard at Oamaru. Unknown date and photographer.Shell had two large bulk fuel tanks at their site while Caltex had two smaller sized bulk fuel tanks. Documents from the archives show that Caltex unloaded tank wagons at their depot and later requested permission to install a raised platform to assist staff in unloading tank wagons.
