Along with a former Speaker of the House, Margaret Wilson, and broadcaster Stacey Morrison and professional company director Brian Corban, Mr Gould will review why Labour attracted just 25 percent support in last month's election.
Mr Gould said it was already clear Labour did not appear to be a united front, and that it failed to connect with a wide range of voters.

He said how the information gathered by the review is analysed and put before the party will be important, so that it was abundantly clear it must not be ignored.
The first part of review will be completed by 7 December.
The party is also in the process of choosing a new leader with Grant Robertson, David Parker, Nanaia Mahuta and Andrew Little all vying for the position.
