Over the last decade, after a set of Open Government Data (OGD) principles were developed, governments around the world started to radically change their culture on data governance. However, at the implementation stage of OGD initiatives governments needed to consider whether publishing the massive quantities of open datasets did meet public needs for use and re-use, in view of the enormous investment and resources put into the production of publishable OGD. This research-in-progress adopts an exploratory case study approach combining it with a narrative literature review to investigate how the “Open by default” principle and the “Publishing with purpose” strategy were involved in facilitating OGD usage and public participation. The study’s goal is to overview the current implementation of OGD initiatives and to explore best practices when working with open data. We expect to present a new logic model or to show the modification of existing government organisational logic models by analysing the findings on the nature of the New Zealand government effort in opening data up relates with the possible advantage experienced by the government and the public at large.
