Shearer favoured, but only just
Voters think Labour leader David Shearer is the most effective opposition leader, but only just.
A TV One opinion poll released on Monday night showed Mr Shearer favoured by 25 percent of respondents, with NZ First leader Winston Peters just behind him on 24 percent.
Green Party co-leader Russel Norman rated 18 percent and Mana's Hone Harawira six percent.
The Green Party's other co-leader, Metiria Turei, was on five percent while 10 percent of those questioned didn't think any of them were effective.
Mr Shearer, who hopes to be the next prime minister, says Mr Peters has been in politics a lot longer than he has.
"I've only been in the job for a few months and people don't know me as well, it's as simple as that," he said.
