This is a list of electoral results for the Division of Werriwa in Australian federal elections from the division's creation in 1901 until the present.
The by-election, as largely expected in the absence of a Liberal candidate, resulted in an easy victory for Labor candidate Chris Hayes. Hayes polled 55.5% of the primary vote, with his nearest challenger being independent Liberal Young on 7.8%, ahead of Green Raue on 5.5%. Locke, despite some predictions of an upset victory, polled only 3.1%.[6] Hayes was able to claim victory on the day of the by-election, and was subsequently sworn in as a member of the Australian House of Representatives. Steven Chaytor, who had stepped aside for Hayes in preselection, later served as a member of the New South Wales Legislative Assembly from 2005 to 2007.
