The Shooters, Fishers and Farmers candidate seeking to replace former Nationals minister Adrian Piccoli in the NSW Parliament says she is "not across" the party's policy of repealing the National Firearms Agreement struck after the Port Arthur massacre and admits: "I don't like shooting much."

Farmer Helen Dalton, the party's candidate for the seat of Murray in the October 14 byelection, says she has a firearms licence for her .22 calibre rifle because "sometimes I've got to put down a sick animal".

But she told Fairfax Media: "I don't like shooting much. But I've got it because I need to have it."

Ms Dalton, 57, said she was aware the party "sort of emerged" after the introduction of "over the top" laws introduced under former prime minister John Howard after the 1996 Port Arthur massacre.
