The NSW Greens have accused the powerful industry lobby group the Australian Hotels Association of "grubby political tactics", after voters in key marginal seats said they were targeted by a push-polling campaign.

Balmain Greens MP Jamie Parker referred the lobby group to the NSW Electoral Commission last week after residents contacted him with reports that they had been subject to a biased poll funded by the AHA.

"This is campaigning masquerading as a poll. The questions being asked of local residents are designed to influence voters to not support the Greens," Mr Parker wrote in the complaint.

One resident, Lesley McFadzean said she thought she was taking part in a standard political survey when she agreed to participate on March 2.
