In particular, adequate information generation and sharing among relevant actors as well as scattering and fragmentation of the generated primary water and environmental data are important bottlenecks across ministries, agencies and levels of government involved in water policy. In addition, substantive problems with data inhibit integrated water policies in several ways (including jargon, a mix of terminologies, unclear definitions, overlapping meanings of terms related to water, etc.). In New Zealand, the lack of common information and a common national frame of reference has historically been the largest hurdle.
