1800s–2000s Glentunnel was served by the
Whitecliffs Branch, a
branch line railway, from the line's opening on 3 November 1875 through to its closure on 31 March 1962. However, the
station was not open until 22 April 1876. In February 1876, the 1600hrs train to Christchurch had left
Whitecliffs when an accident occurred at a sharp bend above the Selwyn Rapids. The
locomotive and
guard's van left the track, causing it to roll down the steep embankment. The engine driver was unharmed, an inspector was slightly injured. The fireman suffered serious injuries, resulting in long-term ill health, where he eventually died. This section of road is now known to locals as "Breakneck Corner". Few remnants of the railway remain in the town, with the station's platform incorporated into the backyard of a private residence. The goods platform can still be seen from Railway Terrace, in amongst farmland. St Luke's
Anglican church used to be situated on the corner of State Highway 77 and Victoria Street. The church was built in 1904, but it caught fire in the 1970s which caused partial damage to the building. It was later demolished. The grounds are now privately owned.
2000–2010 On 18 June 2003, the Glentunnel Community Hall was set alight, causing major damage. The
Malvern Record reports: "At approximately 2.15am on Wednesday the 18th of June the alarm was raised to a fire at the Glentunnel Hall. The call was made by a person travelling through to
Invercargill. When units arrived on the scene the fire had a good hold on the building with the entire building being engulfed in flames. Four units attended the callout; two from
Coalgate and two from Darfield. Also in attendance was a water tanker from the
local council. The fire was brought under control within 15 minutes of the units arriving, with the fire being fully extinguished within an hour. The damage from the road is hard to detect but as you can see from the photographs the damage to the hall is extensive with the entire building being gutted. This is a big loss for the Glentunnel Community." On 28 January 2006, the new community centre was opened, replacing the former hall.
2010 Canterbury earthquake The historic
Homebush Homestead, located four kilometres east from Glentunnel was extensively damaged by the
2010 Canterbury earthquake, so much so that it has been described as being "practically in ruins". It was later demolished and a new homestead was built on the same site. The bell tower of the historic
St John's Church (built in 1911) partially collapsed, causing damage to the
nave and destroying the organ.
2020s–present In May 2021, the Hororata Golf Course (located in Glentunnel) suffered severe damage caused by flooding from the breached
Selwyn River, with it being "largely unrecognisable" as a result. The camping grounds were also evacuated, with campervans and cabins being washed away. It was thought that it would take weeks to repair the damage. ==Demographics==
