Kevin Thomas Campbell is a former New Zealand member of parliament for the Alliance, and the party's leader outside of Parliament at its deregistration in May 2015.

Campbell worked as a milkman, before becoming a police officer. He trained to be a Catholic priest at Holy Name Seminary and Holy Cross College. However he was not ordained. Prior to entering Parliament he qualified as a Barrister and Solicitor and practiced in criminal law.^[1]

Campbell was the Alliance candidate for the 1998 Taranaki-King Country by-election, and claimed to have "played some small part in bringing about the closer working relationship between Labour and the Alliance as a result of that by-election."^[2]

He was a member of the Alliance, having been elected to Parliament as a list MP in the 1999 election, where he stood in the Taranaki-King Country electorate and was placed tenth on the Alliance list.^[3][4]

In April 2002, the Alliance party split^[5] and Campbell did not appear on the list issued later that year, where his party lost representation due to not reaching the 5% vote threshold.^[6][7][8]

Since leaving Parliament Campbell has worked as a Supervising Solicitor at Community Law Canterbury.^[1] Campbell ran again as an Alliance candidate in the Wigram electorate, seeking to be the replacement for out-going MP Jim Anderton but lost, coming fourth, to Megan Woods, a former member of the Alliance & Progressive parties standing on a Labour ticket.^[9]

As of the 2011 election Campbell returned to being an active participant in the Alliance Party and currently sits as the Co-leader of the Party.^{[citation needed]}
