Prasad was a list-only candidate for the
Labour Party on two occasions. At the
2008 election Prasad was ranked 12, the highest-placed new candidate, and was subsequently elected to Parliament. In the
2011 election, Prasad was re-elected, albeit at a lower list placing of 20. He had sought the party's nomination to stand in
Te Atatu in 2011, but was unsuccessful. Prasad sat on the social services committee throughout his two terms as a member of Parliament. He was Labour's spokesperson on the voluntary and community sector (2008–11), ethnic affairs (2011–13) and immigration (2013–14) and an associate spokesperson on ethnic affairs (2008–11, 2013–14) and social development (2008–14). He was believed to have supported
David Cunliffe in the
2011 and
2013 Labour Party leadership contests. As a member of Parliament, he argued against the
National Government's reforms to the Families Commission, which he described as cynical, voted against appointing an anti-abortion doctor to the Abortion Supervisory Committee, voted in favour of
legalising same-sex marriage, and said he would not vote in the
2009 New Zealand child discipline referendum. He was also an advocate for ethnic communities and immigrants. However, Prasad was seen by media as being ineffectual and unlikely to be appointed to a ministerial office if Labour were to win an election. For each of the three years from 2011 to 2013, political newsletter
Trans Tasman rated his performance 1/10; a November 2013
Dominion Post editorial suggested that he be told not to run again;
The New Zealand Herald reported he only issued a single press release that year. In May 2014, Prasad announced his plans to retire ahead of the
general election in September 2014. In his valedictory speech, given on 24 July, he commented on the limitations on the effectiveness and perceptions of ethnic MPs in the "largely monocultural" New Zealand Parliament: After leaving Parliament, Prasad was appointed a
Commonwealth Envoy with special responsibility for
Lesotho working directly in Africa to help develop better political practices. == Honours ==
