“It’s not a large surprise ... we collected everything in the field.” Artefacts found were sent in 600 boxes to NZ Heritage Properties’ main office in Dunedin. After analysed and documented, consignments of artefacts were sent back to Invercargill Central Ltd. Included in the latest consignment were an old beer bottle from 1910, a 1870s Torpedo soda bottle and a leather boot manufactured before 1905. Marked on the beer bottle was: Digger brand, Whittingham & Co Waikiwi, Ale stout. “The Torpedo soda bottles were designed to always sit on their side to keep the cork wet and to keep the pressure, so the drink doesn’t go flat,” Woods said.
