Golden Bay Cement switches cement transport through Northport

Auckland, May 4

Golden Bay Cement has started shipping cement directly out of Northport, supporting Northland’s economy.

It is using Northport’s container lifting capability and a newly-introduced fortnightly coastal shipping service to improve the way it moves cement powder from its plant in Portland, near Whangarei, to its domestic New Zealand distribution hubs.

Fletcher Building’s Building Products Chief Executive David Thomas says: “We are really excited to be able to now send our cement through Northport, which means more direct business for Northland.”

Since starting shipping out of Northport in late September last year, the cement factory, which is based near Whangarei and is New Zealand’s only cement factory, is working up to moving about 11% of its overall production to the South Island in this way.

Using Northland’s port to shift cement was made possible by a $30 million investment in the factory’s facilities as part of the factory’s centenary celebrations last year, including a new silo capable of taking the necessary containers.

GBC Winstone Head of Cement Paul Thorn says: “We distribute cement to the southern half of the South Island in tanks that are based on a 20’ container footprint; colloquially know as ISO Pods. Each pod carries a minimum of 23 tonnes of cement. We have approximately 700 pods in total that are in circulation between Portland and the South Island, which are carried by a flat deck truck between the plant and port. Portland has only had the capability to fill these tanks with the commissioning of Silo 9, as we required sufficient head height for the truck and tank to enter under the silo for filling.”

“Prior to Portland having Silo 9, the cement was shipped directly from our Portland dock to Auckland where ISO Pods were filled from our Eastport facility. So we were effectively double handling the cement for the South Island through Eastport. Now we fill these pods in Portland and a shipping service to Lyttelton has been established from Northport. So this initiative has improved handling efficiencies, and redirected this business to Northland.”

GBC Winstone, owned by parent company Fletcher Building, also uses its chartered ship MV Aotearoa Chief, to make over 60 voyages each year directly from the cement plant near Whangarei to distribution centres in Auckland, Tauranga, Napier, Wellington, as well as expanded services to New Plymouth and Picton.
