He is an advocate for non-official or track two diplomacy. In a submission to the New Zealand government's 'Seriously Asia' conference in 2003, he expressed concerns about the country's commitment to understanding Asia. In particular, he lamented the lack of resources allocated to the work of think-tanks and track two organizations. Cozens has been quoted as saying the New Zealand Defence Force also needs to increase its expertise, in particular that there is a "need to lift the academic ability of our officer cadre: this is well overdue for real professional development." As former Executive Director of the Centre for Strategic Studies, Cozens' duties include directing research, giving speeches, providing media commentary and contributing to the School of Government's Masters of Strategic Studies degree. He managed several full-time staff members, and also oversees a number of the Centre's Senior Fellows, including former director Terence O'Brien, University of Auckland academic Stephen Hoadley, and Lance Beath. Cozens has also increasingly found himself raising money to support the Centre's activities. He is also a Fellow of the Asia/Pacific Research Institute of New Zealand and serves on the Editorial Board of the Sea Power Centre - Australia working paper series.
Views on security issues
Cozens has outlined his own views on strategic policy and security issues in numerous papers and books on terrorism, security and maritime cooperation in the Pacific-Asian region. In a 2005 newspaper interview, he called for a "softly softly, catchy monkey" approach to counter-terrorism, saying it would "reward authorities more than a 'reds under the bed', or 'terrorist under the bed' approach." In response to an Australian report that warned about future resource competition in the Antarctic, Cozens said the New Zealand Government "should think in terms of increasing New Zealand's military presence" near the south pole. The idea was not welcomed by the New Zealand Defence Force. In an article in the Australian journal 'Security Challenges' he argued that the New Zealand Defence Force should be renamed the "Armed Services of New Zealand" to reflect the fact that it increasingly performs a range of non-traditional functions. Cozens' views have not found universal support. A letter to The Listener magazine in May 2006 described him as an "ex-navy wallah" who needs his "head read".
Health issues
In early 2007 Peter Cozens was taken to hospital for stress related heart problems related to overwork. He recovered well. In 2009, he retired.
