The household spoke te reo Māori as their first language and Morgan once stated the only time English was spoken was when he would read aloud from the newspaper to his grandfather.

[2] In the 1980s, Morgan attended a Māori land protest where he was convicted of obstructing a police officer and ordered to do community service.

[5] Later, he was involved in the establishment of the short-lived Aotearoa Television Network, New Zealand's first Māori-language broadcaster, which began operations in 1996.

Morgan was the network's head of sport, youth and current affairs programmes and also a news presenter.

[7] He had been expected to be the government's nominee to chair the Māori affairs committee, but withdrew his nomination because of a controversy early in the term.

[8] In February 1997, it emerged that two weeks before the general election, Morgan had spent $4,000 of Aotearoa Television funds on clothes including an $89 pair of Hugo Boss underpants, among other alleged financial misuse by the company's directors.

[11] The expenditure was controversial because the Māori affairs minister, Morgan's brother-in-law Tau Henare, had announced $4 million of new government funding for the network the month prior (the provision of which was later withdrawn).

The bill was considered and endorsed by the Māori affairs committee and approved for continuation by Parliament in a 111-7 vote on 1 September 1999.

[15] Morgan also promoted the Smoke-free Environments (Enhanced Protection) Amendment Bill in July 1999, which was transferred to Steve Chadwick after the election.

[17] Morgan was chair of Te Arataura, the Waikato-Tainui executive board, from 2003 to 2004, when he was removed from office because of a criminal conviction for obstructing police during a protest march in the 1980s.

[25] In August 2018, he published an open letter to the Māori King Tūheitia Paki, whose advisor he had previously been, detailing a number of criticisms of Paki's behaving, including his continued support and employment of Rangi Whakaruru as chief of staff.
