This quote was made by the British Prime Minister Boris Johnson on January 4th, 2022. It shows the desire not to shut down the country by implementing another lockdown despite the highly infectious Omicron variant of the Covid-19 virus. This quote shows his perception on the virus, whilst on the other side of the world, Prime Minister Ardern had closed the national borders of New Zealand back in 2020 which have remained closed until further notice. This difference in policy adoption and decision-making processes between two countries which are seemingly very similar in terms of the economic stability, political stability, territory size, and collaborative international partners is very puzzling. This research will therefore concern the identification of the core cause of this difference in policy adoption. The research has been conducted through the use of official governmental legislative documents as well as reliable secondary sources in order to conduct a comparative small-N design-based research. The method of this small-N design is the Most Similar Systems Design II method which aims to uncover the key cause of the difference in outcome of a specific case. For this research, the theories by Kingdon (Kingdon, 1984) ; (Béland & Howlett, 2016) and Dai et al. (Dai, et al., 2021) are used.Show less
