of string picking. One example of "Te Reo Metal" is the Thrash metal band, Alien Weaponry. By the 1970s, Māori music had become a very minor part of New Zealand broadcasting. In 1973, only 15 minutes of Māori music was played on New Zealand airways per week. In the 1980s, a number of sungs sung in te Reo became hits in New Zealand, including "The Bridge" (1981) by Deane Waretini, "Maoris on 45" (1982) by the Consorts and "E Ipo" (1982) by Prince Tui Teka. The largest of these was "Poi E" performed by the Pātea Māori Club, which became the top single of 1984. After the 1986 Te Reo Māori claim at the Waitangi Tribunal (Wai 11), which argued that Māori language was a taonga (treasure) that the New Zealand Government was obliged to protect, Māori music and Māori language broadcasting became used as a means to promote Māori language and culture. In the 1980s and 1990s, local iwi radio stations were established in New Zealand, and in 1990 the government reserved radio frequencies specifically for the promotion of Māori language and culture. These stations included Radio Waatea, Radio Tainui, Tahu FM and Mai FM (which was later sold to MediaWorks as a commercial urban contemporary radio station). Two government agencies began to fund Māori music: NZ On Air and Te Māngai Pāho. In the 1990s, musicians such as Moana and the Moahunters, Southside of Bombay and Hinewehi Mohi ("Kotahitanga") released high profile songs that were sung in or included Te Reo Māori lyrics. Many Māori musical acts since the 1980s have been influenced by African-American music genres and reggae. From 1998 until 2010, NZ On Air produced compilation albums of Māori music for radio stations, entitled Iwi Hit Disc, in a similar vein to the organisation's Kiwi Hit Disc series. These albums were intended to showcase Māori music which had potential crossover potential to other radio formats. During this time period, very few songs sung in Māori had major success. In 2014, as a challenge to repeat the success of "Poi E", musicians Stan Walker, Ria Hall, Troy Kingi and Maisey Rika released the song "Aotearoa" for te Wiki o te Reo Māori. The song reached number two on the New Zealand singles chart. In 2019, to mark the 20th anniversary of the 1999 Rugby World Cup semi-final where Hinewehi Mohi performed the national anthem in te reo,
