Context: Since the 1990s, there has been consolidation in New Zealand's state-owned tertiary education system. In the polytechnic sector: Wellington Polytechnic amalgamated with Massey University. The Central Institute of Technology explored a merger with the Waikato Institute of Technology, which was abandoned, but later, after financial concerns, controversially amalgamated with Hutt Valley Polytechnic, which in turn became Wellington Institute of Technology. Some smaller polytechnics in the North Island, such as Waiarapa Polytechnic, amalgamated with UCOL. (The only other amalgamations have been in the colleges of education.)
