Tuakiri is New Zealand’s national access federation service for the higher education and research. Tuakiri defines policy and operates central infrastructure to support coordinated approaches to identity management, authentication and authorization between institutions in New Zealand, enabling shared services and higher degrees of collaboration and efficiency across the sector. This enables federation users to securely and easily access federated resources or services at remote locations using a single set of credentials provided by their home institution. There are sixteen IdP institutions, eight NZ Universities and eight Crown Research Institutes, and potential to provide the service to the twenty Polytechs. There is also the opportunity to expand the service into the NZ Compulsory School Sector in the near future.
