levels vary widely. 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.) The Auckland University of Technology is the only polytechnic to have been elevated to university status; while Unitec has had repeated attempts blocked by government policy and consequent decisions; Unitec has not been able to convince the courts to overturn these decisions. In mid-February 2019, the Minister of Education Minister Chris Hipkins proposed merging the country's sixteen polytechnics into a "NZ Institute of Skills and Technology" in response to deficits and a decline in domestic enrollments. The proposed merger will be subject to a six-week consultation period until 27 March. Nigeria Virtually, every state in Nigeria has a polytechnic university operated by either the federal or state government. In Rivers State for example, there are two state-owned polytechnic universities; Kenule Beeson Saro-Wiwa Polytechnic, Bori City and the Rivers State College of Arts and Science, Port Harcourt. The former was established on 13 May 1988 while the latter–though founded in 1984–was approved by the NBTE in 2006. The first private polytechnic university in the state is the Eastern Polytechnic, established in 2008. Pakistan The polytechnic institutes in Pakistan offer Diploma in Engineering spanning three years in different engineering branches. This diploma is known as Diploma of Associate Engineering (DAE). Students are admitted to the diploma program based on their results in the 10th grade standardized exams. The main purpose of the diploma offered in polytechnic institutes is to train people in various trades. These institutes are located throughout Pakistan and started in early 1950s. After successfully completion of diploma at a polytechnic, students can either get employment or enroll in Bachelor of Technology (B.Tech) and Bachelor of Engineering (BE) degree programs. Universities of Engineering & Technology in Pakistan offer undergraduate (BE/BS/BSc Engineering) and postgraduate (ME/MS/MSc Engineering and PhD) degree programs in engineering. BE/BS/BSc Engineering is a professional degree in Pakistan. It is a four-year full-time program after HSSC (higher secondary school certificate). Palestine
