Over recent years, the National Library of New Zealand (NLNZ) has moved towards aggregating its online collections and high-tech resources under an initiative called the National Digital Heritage Archive (NDHA). The NDHA built its own Web tools and designed clean interfaces to make users' experience easy and intuitive. NDHA also partnered with Ex Libris and Sun (now part of Oracle) to develop an OAIS compliant repository.
The NDHA also has a great deal of support from their government, which is upgrading the country's overall cyberinfrastructure to help improve their economy and make New Zealand competitive worldwide.
