The characters from Conjugal Rites reappear in Hall's final play to date, Winding Up, which premiered at the Auckland Theatre Company in 2020. He was co-writer with Philip Norman and A K Grant of Footrot Flats the Musical, which has had more than 120 productions in New Zealand and Australia. Their follow-up collaboration, Love Off the Shelf, premiered at the Fortune Theatre, Dunedin, in 1986. It had two pre-West End try-out productions in the United Kingdom, the second in 1993 directed by Sir Alan Ayckbourn at his Scarborough Theatre, and the libretto was published by Samuel French Limited. In recent years, his plays Who Wants to be 100? (Anyone Who's 99) (2008), Four Flat Whites in Italy (2009), and A Shortcut to Happiness (2011) had hugely successful runs throughout New Zealand. His show about grandparenting, You Can Always Hand Them Back (2012), has songs by British performer/songwriter Peter Skellern, and has been performed throughout New Zealand and had a season in the UK. Hall has had many plays, series, and talks on radio, including The Dream Factory for the BBC. Hall has contributed to the arts in several other ways. Most notably he organised the first NZ Writers' Week, held in Dunedin in 1989, where twenty-nine NZ writers appeared, NZ plays were performed, and various exhibitions linked to local writing were held. Thousands of people attended, and another Writers’ Week was held two years later, and the event continues in Dunedin in a modified form every two years. In 2005, he arranged for a scene set on Takapuna Beach on Christmas Day in the 1930s from Bruce Mason's one-man play The End of the Golden Weather to be performed on Takapuna Beach on Christmas Day. Actor Stephen Lovatt does the one-man show that is presented every year. It has now become an established tradition, with up to 500 people attending the free event. OXFAM benefits from a collection and Lovatt donates his fee to the same charity. In the 1980s, Hall set up a society to improve children's television (Monitor) and has also served on many arts boards and organizations including the NZ Literary Fund Advisory Committee, the Dunedin Public Art Gallery, chairman of Fortune Theatre Board, Frank Sargeson Trust, Janet Frame Eden Street Trust, and Governor of the Arts Foundation of New Zealand. Hall's autobiography, Bums on seats, was published by Penguin Books in 1998. He has also written
