Former AMP chairman Peter Mason has survived strong opposition from proxy investors to his re-election to the same role at AusNet Services, only thanks to major shareholders Singapore Power and China State Grid standing firmly behind him.

Proxies voted ahead of Thursday's annual general meeting, came in 57.3 per cent against Mr Mason's re-election as a director, following the recommendation of two major advisers that raised worries over previous "failures of governance, stewardship and risk oversight" identified at AMP in the banking royal commission.
