A former campaigner for Tukituki National MP Craig Foss says Tukituki Labour candidate Anna Lorck knowingly supported National when she volunteered at a National Party base during the 2011 election.
But Ms Lorck maintains she was never a National Party supporter.
The election-day organiser of Craig Foss' campaign team in 2011, Jo Harvey, told Hawke's Bay Today she approached Ms Lorck to volunteer on the phones of Tukituki's National Party base on election day because she was on a mailing list of National supporters.
Ms Harvey said Ms Lorck had agreed to volunteer, stating that she was a "front-line type of girl," and offered to volunteer more of her time "if there's anything else you need".
"When I approached Anna Lorck, I told her what organisation I was from and at no point did she ask to be removed from the [mailing] list."
