Carparking takes up the lower tower floors to about the height of the old buildings, with office space above that.

The building is owned by Precinct Properties and was renamed to Dimension Data Tower in March 2017.[4] With the global name change of Dimension Data to NTT in 2019,[5] the building's name and branding changed yet again. The building already houses, or has housed, many of New Zealand's top technology companies such as Microsoft New Zealand, Provoke Solutions, Google NZ, as well as tech start-ups such as SuiteFiles. Midland Park has built up a reputation for being the IT centre of Wellington and is surrounded by many government departments.[6]
