Former MP Jim Anderton will be farewelled at a ceremony today.

Mr Anderton died peacefully last week at the age of 79 in Christchurch, where he had served as the Sydenham and Wigram MP from 1984 until his retirement from Parliament in 2011.

A Requiem Mass will be held for Mr Anderton at Sacred Heart Catholic Church, 70 Spencer St, Addington at 2pm.

The service is open to the public and will be live-streamed.

Mr Anderton’s legacy has been praised since his death, from his principled stance in 1989 when he left the Labour Party in protest over Rogernomics and the sale of BNZ, to his championing MMP as leader of the Alliance.

His work in the Helen Clark-led Government included helping to set up KiwiBank, the NZ Superannuation Fund, paid parental leave and several regional development initiatives such as the Marlborough Wine Research Centre.

After he retired, he served as chair of the Stadium Trust and pushed for the rebuild of the ChristChurch Cathedral.

Last year, Mr Anderton was made a Companion of the New Zealand Order of Merit for services to Parliament.
