NeSI Support Documentation

Technical documentation for the NeSI High Performance Computing platform.

REANNZ Integration

On 01 July 2025, the roles, services and technologies of NeSI were integrated into the crown-owned company, Research and Education Advanced Network New Zealand (REANNZ), centralising New Zealand’s eResearch infrastructure.

All NeSI services and support – including these Support Documentation pages and team monitoring the support@nesi.org.nz email – are continuing as you’ve known them. Also, the principles of our policies (Access, Acceptable Use, Security & Privacy, etc.) are carrying over and remain in effect. We'll be in touch if anything changes. If you have any questions about the NeSI-REANNZ integration, Contact our Support Team
