Between 1987 and 1989 he was a consultant for the Tainui Trust Board assisting with the preparation of its land claims to the Waitangi Tribunal. In 1989 he was appointed as UN Co-ordinator for Humanitarian Operations in Africa and the Balkans and served as head of the Save the Children Fund in Rwanda, Somalia, Northern Iraq and Sri Lanka.[1] In 1995 he served as the Senior Humanitarian Affairs Adviser in Liberia.[6] From 1999 Shearer served in various UN posts including Deputy Humanitarian Coordinator for the United Nations in Rwanda, Senior Humanitarian Adviser in Albania and Chief of the United Nations Office for the Coordination of Humanitarian Affairs in Belgrade.[6] Shearer left the United Nations to work as an adviser to the Minister for Foreign Affairs and Trade, Phil Goff for two years.
In 2002 Shearer returned to the United Nations, serving as a Senior Adviser to the United Nations Assistance Mission in Afghanistan.[6] In February 2003 Shearer was appointed head of the United Nations Office for the Coordination of Humanitarian Affairs in Jerusalem.[6] During the conflict in Lebanon in 2006 he served as the Humanitarian Coordinator organising assistance for civilians caught up in the conflict between Israel and Lebanon.[7]
In 2007 Shearer was appointed by the United Nations Secretary-GeneralBan Ki-moon as his Deputy Special Representative (Humanitarian, Reconstruction and Development) for Iraq.[6] While in Iraq, Shearer also served as the United Nations Resident Coordinator and the Humanitarian Coordinator. In this role he was responsible for managing over $2 billion in aid for developmental projects for 16 different UN agencies.[1]
In March 2013 Shearer admitted he had not declared a US-based bank account in which he received his salary from the UN, saying he had simply forgotten about it.[8]
Before his election as a Member of Parliament Shearer had twice previously stood for the Labour party: in 1999 he stood as a list-only candidate and in 2002 he unsuccessfully contested the Whangārei electorate.[9] In May 2009 he returned to New Zealand and won the Labour Party nomination for Mount Albert against seven other candidates.[10] He then won the 2009 Mt Albert by-election on 13 June 2009 with 13,260 votes, a majority of 9,718 over National's Melissa Lee.[11] Shearer extended his majority over Lee to 10,021 in the 2011 general election.[12] In the 2014 general election, Shearer further extended his majority over Lee to 10,656.[13]
In December 2011, following the resignation of Phil Goff, Shearer contested for leadership of the Labour Party. His opponents were David Cunliffe and David Parker. Shearer was viewed as unlikely to win the election; Claire Trevett of The New Zealand Herald originally expected that only Cunliffe and Parker would run for the leader's role,[14] and The Dominion Post's Vernon Small wrote that "Mr Shearer's bid is seen as a way to lift his profile".[15] On 9 December, Horizon Research released a demographically weighted survey which found that 35.4% of adult New Zealanders supported Shearer's bid for the leadership, and 19.9% backed Cunliffe.[16]
On 13 December, Shearer was elected by the Labour caucus. Both One News' Espiner and 3 News reported that Shearer received about twenty-two of the thirty-four votes for the leadership position;[17][18] however, Party President Moira Coatsworth stipulated that the election was secret and that she was the only person who had access to the ballot papers, which were destroyed.[19]
Political commentators opined that Shearer was moving the Labour Party towards the centre.[21] Polls suggested that his performance as leader was rated unfavourably with the public, and he had poor name recognition. He was described as "the invisible man of New Zealand politics".[22]
In November 2012 during a Labour Party conference, media speculation suggested that Cunliffe, who was then economic development spokesperson, would launch a challenge against Shearer for leadership of the party.[23] On the morning of 19 November, Cunliffe confirmed he was not challenging Shearer, and would indeed back him if a vote was taken. However, he also said he would not commit to supporting Shearer when he faces a formal confidence vote in February 2013. Media speculation about Cunliffe's intentions marred Shearer's first 12 months as leader.[24] Labour MPs unanimously endorsed leader Shearer at the annual conference, and Shearer subsequently demoted Cunliffe from the front bench.[25]
During Shearer's leadership the Labour Party floated a controversial proposed policy of not considering males for candidate selection. Dubbed the "man ban", the policy was to ensure that 50% of Labour MPs were female by 2017 and allowed local electorate committees to hold all-women shortlists to reach this goal.[26] The policy received backlash with many Labour members (including women) being opposed thinking it discriminatory.[27] After initially remaining silent on the policy, Shearer publicly stated his opposition to the "man ban", noting he was supportive of more women in parliament but the policy was not the right mechanism for it. The policy was subsequently discarded.[26]
Shearer continued to face dissent within the party caucus. On 20 August 2013, a stunt involving Shearer holding up two dead snapper in Parliament, while questioning the Government about proposed changes to recreational fishing management, was not well received.[28][29][30] He announced his resignation as Labour leader on 22 August 2013, stating that: "My sense is I no longer have the full confidence of many of my caucus colleagues".[31][9] Following a party-wide leadership election, Cunliffe was elected Shearer's successor over Deputy Leader Robertson.[32]
Cunliffe appointed Shearer to his Shadow Cabinet as spokesperson for Foreign Affairs and also Energy and Resources.[33]
