While still enrolled at Victoria University, Gibson began part-time work for the New Zealand Broadcasting Corporation. This mainly involved labour, moving sets from in Lower Hutt to the corporation's Waring Taylor Street locations. In 1977, Gibson left his degree unfinished and established Gibson Films, in a rented office on Courtenay Place in Wellington. He began mining the genre of educational films, which he would then sell to schools and educational film distributors. One early piece about two children living on a high country sheep station sold to Encyclopædia Britannica. In the 1980s Gibson Films rebranded to The Gibson Group, and their genre offering widened. Early productions included The Silent One, an adaptation of the Joy Cowley novel of the same name, filmed entirely on the small island of Aitutaki in the Pacific. It was also the first NZ feature film directed solely by a woman. During this period, sketch comedy also became one of the mediums Gibson Group became known for. Satirical puppet show Public Eye, inspired by the UK show Spitting Image, proved popular despite having to be toned down for NZ audiences. Other genres included magazine-style shows The Edge, Sunday, B@ckchat and Frontseat. Throughout the 1990s and into the 2000s, The Gibson Group broadened their mediums to work with interactive museum exhibitions both in New Zealand and overseas, including Our Space at Museum of New Zealand Te Papa Tongarewa. The popular children's shows The Simon Eliot Show and MyStory used cellphones and technology to let the audience interact with the host. MyStory was New Zealand's first show screened in a 'mobisode' format. Gibson's other notable productions include two natural disaster dramas for television. Aftershock, an earthquake drama accompanied by a documentary and website about earthquake safety. This was followed by Eruption, set in Auckland's volcanic landscape. In the 2012 Queen's Birthday and Diamond Jubilee Honours, Gibson was appointed an Officer of the New Zealand Order of Merit, for services to the film and television industry. In 2013, Gibson was appointed CEO of the New Zealand Film Commission. During his tenure the commission granted funding for successful New Zealand films such as Tickled, Poi E: The Story of Our Song, Mahana, and Pork Pie. Gibson is currently a board member of the Wellington Regional Economic Development Agency. In June 2017, Gibson announced that he would be stepping down from the role of CEO. In a statement, Gibson said "I've thoroughly enjoyed the last few years but have always believed CEO's shouldn't stay too long in organisations like the NZFC. I'm not sure what I'll do next."
