Three Cray supercomputers —Māui, Mahuika and Kupe—make up the High Performance Computing Facility.
- Māui and Mahuika are housed at NIWA’s Wellington campus. Kupe is sited at the University of Auckland's Tamaki Data Centre.
- Together the three computers are capable of processing more than two thousand trillion calculations per second.
- The HPCF contains more than 14 petabytes of high performance storage along with 200 petabytes of archive storage and all scientific data is fully backed up.
- The facility housing Māui and Mahuika features the latest heat transfer technology cutting cooling costs by half.
- The facility has been specially constructed to withstand both seismic and tsunami threats.
