The by-election for the Gosford electorate takes place on Saturday, April 8.
The State Seat was vacated by Labor MP Ms Kathy Smith due to illness, triggering the by-election.
One of the most marginal seats in the state, Gosford was narrowly lost by former Liberal MP Mr Chris Holstein in 2015, before it was picked up by Labor.
Ms Smith suffered from ill-health for the majority of 2016, and announced her resignation in February 2017.
Prior to Mr Holstein, the seat was held Ms Marie Andrews for Labor from 2007 to 2011, when a change in electoral boundaries saw the disappearance of the Peats electorate, which had covered the Peninsula.
The Gosford electorate had previously not included the Peninsula.
Peats had been held since 1995 by Ms Andrews, and by Labor since its inception in 1973.
The electorate of Gosford is now 867.15 square kilometres and covers postcodes 2083, 2250, 2256, 2257 and 2775.
