Premier Gladys Berejiklian and her deputy, Nationals leader John Barilaro, will meet on Wednesday to decide which Coalition party is best placed to contest Wagga Wagga in a byelection.

The NSW Liberals were polling voters in Wagga Wagga last night, following a round of National Party polling in the seat on Monday night.

Liberal Party sources have confirmed the two will take their polling results to the meeting to nut out an agreement over who should run in the regional NSW seat.

This is despite Ms Berejiklian's comments on Monday, in which she said the Liberals would be the only Coalition party to run in Wagga Wagga.
