Goff on MPs with second jobs

The Herald reports:

Mr Goff expected the byelection to be close.

He said Ms Laban’s new job was not something she could have delayed until the next election, nor could she have done it at the same time as being an MP.

So Phil Goff is saying that one can’t take up an academic appointment and be an MP, but his party is fully backing Jim Anderton in his desire to be a Mayor, an MP and a party leader?
