Some NSW voters have had trouble casting their ballot as issues plaguing the state's electronic voting system ran into election day.
Technical issues began on Friday night but continued Saturday morning as thousands flooded iVote to register and cast their ballot.
Frustrated voters then turned to the telephone registration system, which itself was then overloaded, with some told to call back later.
However, the NSW Electoral Commission has stressed that registration and voting is working.
"There have been some intermittent performance issues that have affected some electors," a spokeswoman said in a statement on Saturday afternoon.
