Lake Puketirini
Lake Puketirini is a former opencast coal mine, immediately to the west of Huntly and east of the larger, but much shallower Lake Waahi, in the Waikato Region. It is circled by a walkway.
History
The area was initially known as Puketirini, which included Lake Rotoiti, which was shown on maps until 1949, though a 1944 map showed it as Westmere and drained. The west shaft of Ralph Mine was at Puketirini and used for rescue after the 1914 explosion. The site was identified as a potential coal mine in 1929 and land was bought by the government between 1940 and 1980.Mining began on part of the site in 1954, or 1956. The initial mining used small excavators. From 1984 the mine was extended to the north. It was transferred to the Coal Corporation in 1986 and Weavers opencast coal mine excavated the area until 1993, using a bucketwheel excavator and conveyor belt to dig out of overburden and of coal, mostly for Glenbrook steelworks. Much of the area around the lake is unconsolidated overburden.
The shoreline was shaped by 1999 and the lake was full by 2005. In December 2006, Waikato District Council acquired part of the site for recreational use from Solid Energy.
