He attended Hampden Street School, Nelson College Preparatory School and Nelson College, the latter two from 1963 to 1969. Later, he was educated at Victoria University of Wellington, New Zealand where he gained two degrees: one in law and the other in political science.
He was an Member of Parliament from 1990 to 1996, representing the Labour Party. Blincoe currently lives in Wellington and has two children. Blincoe served as the President of NZUSA during 1976.
Blincoe was first elected to Parliament in the 1990 elections as Member of Parliament for Nelson, replacing the outgoing Philip Woollaston.
He was re-elected in the 1993 elections, but in the 1996 elections, the seat of Nelson was expanded into rural areas formerly part of the Tasman electorate. Blincoe was defeated by the incumbent Tasman Member of Parliament, Nick Smith of the National Party.
In the 1999 election, Blincoe missed out on a seat, as a list candidate under mixed-member proportional (MMP) representation, by a narrow margin once special votes had been counted. Initially it appeared that Blincoe would have a seat in Parliament, as well as a party member directly following him on the Labour party"s list.
With the counting of special votes, however, the Green Party crossed the minimum 5% threshold of votes and received an electorate Member of Parliament, which in turn allowed them to have seats in Parliament.
Once seats had been proportionally re-allocated with both the Green Party and New Zealand First in mind, fewer list seats were available for other parties, and consequently John Blincoe was not allocated a seat.
Prior to becoming a member of New Zealand"s Parliament, he had been employed by the Wellington City Council as well as by the Accident Compensation Corporation.
