Mount Kaukau () is a large hill in the northern suburbs of Wellington, New Zealand near Johnsonville, Khandallah and Ngaio. The summit is above sea level and is the most visible high point in the Wellington landscape further accentuated by Wellington's main television transmitter mast, which stands from the summit. The city, harbour and the Remutaka and Tararua Ranges can be seen from the summit. On a clear day Mount Tapuae-o-Uenuku and the Kaikà Âura Ranges in the South Island may be seen, whilst northwest is the Porirua Basin and the Tasman Sea.
The hill's original name TarikÃÂkàmeans 'where the parrots rested' and is shared with the nearby settlement in Ngaio at the base of the mountain. Before the clearing of the native tà Âtara forest on the slopes and general area, the native parrot kÃÂkàwas common through the city. Over a hundred years later today, the population of kÃÂkàhas begun to regenerate thanks mostly to the efforts at Zealandia, and are becoming a more regular sight throughout the city and in the rejuvenating native forest on the slopes of Mount Kaukau.
Much of the eastern 'city side' slopes of Mount Kaukau make up Khandallah Park, which is one of the oldest parks in New Zealand, established in 1888 and then registered as a domain in 1909. Khandallah Park has more than 60 hectares of native forest. Native birds such as the kererà «, tà «Ã« and New Zealand fantail are common sights when walking through the native forest. Stumps of the old totara trees can also be seen walking through the first lower parts of the forest. In mid 2017 an old bunker off Woodmancote Road, at the base of Mount Kaukau, was rediscovered after it had been sealed off and forgotten many years previously. The bunker in an 'H' shape, had been built for Royal New Zealand Signals Corps in 1942. Due to poor construction the bunker was very leaky and was never used. Mount Kaukau forms part of the Northern Skyline track from Johnsonville to Karori and Makara.
Khandallah Park has 9 kilometres of walking tracks allowing access to the peak of Mt Kaukau from Khandallah, Johnsonville, Ngaio and Crofton Downs. Some tracks are also open to mountain biking and e-biking.
The Mount Kaukau television transmitter was approved for construction in February 1965, at a cost of ã410,000. It incorporated 100 kW television transmitter and a 122-metre transmission tower to transmit television channel WNTV1 (now part of TVNZ 1). The new transmitter would be ten times as powerful and offer a much improved coverage area over WNTV1's existing transmitter at Mount Victoria.
Today, the Mount Kaukau transmitter is the main television and FM radio transmitter for the Wellington metropolitan area.
In May 2022, Kordia removed the top 18 metres of the aerial, as the section was redundant following the end of analogue television broadcast.
The UHF TV antennas are located 93 metres up the tower, while the FM radio antennas are located 65 metres up the tower.

The following frequencies were used until 29 September 2013, when Kaukau switched off analogue broadcasts (see Digital changeover dates in New Zealand).
Every year Khandallah School, which is at the base of Mount Kaukau, organises a fun walk / fun run from the school to the summit and back, called the Kaukau Challenge. The Kaukau Challenge has been an annual event since 2006 with about 500 people taking part each year.
In mid-August 2011, two Wellington men, Nick Fone and Daniel McFadyen claimed to be the first people to ski and snowboard down Mount Kaukau when they took advantage of the unusual weather pattern delivering snow to most parts of the North Island. As Wellington has a temperate climate, snow down to near sea level is extremely rare, happening less often than once every 15 years.
