Abstract
Three out of five research outputs by Otago authors in 2017 are behind paywalls as of June 2019. Of the 868 articles that are behind a paywall, 84% of these could be deposited legally in a non-commercial repository to make them free-to-access. This is despite a citation advantage of 93% for research that is openly accessible. Where open access was achieved by a paid method (Article Processing Charges) this was estimated to have cost NZ$735,000 for 2017.
