E 30 ngā tau i mahi a Ron Crosby hei rōia i roto i te kōti, otirā ki ngā kēhi hāngai ki te Tiriti me ngā kēhi whakahaerenga rauemi. He kaikōmihana nohoanga, he kaikōmihana wai māori hoki i raro i te Resource Management Act 1991. Kua tuhi ia i ētahi pukapuka e pā ana ki te hītori o Aotearoa, tae atu ki The Musket Wars: A History of Inter-Iwi Conflict, 1806–1845 (1999), Gilbert Mair: Te Kooti’s Nemesis (2004), NZSAS: The First Fifty Years (2011), Kūpapa: The Bitter Legacy of Māori Alliances with the Crown (2015), The Forgotten Wars: Why the Musket Wars Matter Today (2020) and Te Kooti’s Last Foray (2023). E kaingākau nui ana a Crosby ki ngā tuawhenua me te hītori o Aotearoa. E whakakahangia tonutia ana tana aronga ki te ao Māori e ana hononga ā-whānau, nō Te Rarawa me Te Aupōuri tana wahine, a Margy. I kopoua a Mr Crosby ki te Taraipiunara i te tau 2011.
