Tony Abbott and Julie Bishop are more popular with voters than Malcolm Turnbull in the NSW seat of Orange, according to polling obtained by Fairfax Media.

The poll of 725 voters, conducted on Monday night by ReachTEL for NSW Labor, comes ahead of a crunch byelection in the state seat on November 12.

Voters in the seat were asked who they considered was the better prime minister and were given three choices - Mr Turnbull, Mr Abbott and Ms Bishop.

Just 32.6 per cent of voters nominated Mr Turnbull as better prime minister; 33.7 per cent of voters nominated former prime minister Mr Abbott and 33.8 per cent of voters nominated deputy Liberal leader Ms Bishop.
