This map shows the location of the tunnels and caverns around Arras, where the New Zealand Tunnelling Company was active from 1916 to 1918. From Russell in the north to Bluff in the south, the parts of this tunnel system were identified by New Zealand place names. The town of Arras is just to the north-west of the area shown on this map.
The thin red and thick black lines at bottom right show the location of the British and German front trenches in 1916. 'Guernsey', at top right, was part of the main British tunnel system, which featured place names such as London, Carlisle, Liverpool and Glasgow.
