The Association of Staff in Tertiary Education (ASTE) is a national trade union in New Zealand. It was formed in 1988 by the merger of the Teacher Colleges Association (TCA), and the NZ Association of Polytechnic Teachers (NZAPT). The majority of members are from polytechnics. However, it retains coverage of the academic staff at the Auckland University of Technology (AUT) and has members at the Victoria, Massey, Waikato and Auckland universities who were employed at the former Wellington Polytechnic and former colleges of education before these institutions were merged with the universities. Most of the other staff at the seven established universities belong to the Association of University Staff, although some belong to the Public Service Association (PSA) and the Service and Food Workers Union. ASTE & Association of University Staff (AUS) have elected to amalgamate to become New Zealand Tertiary Education Union (NZTEU) effective 1 January 2009 The ASTE is a member of the New Zealand Council of Trade Unions.
