Bill English and Jacinda Ardern tonight square off against each other for the last time before Saturday's vote.
Newstalkzb Political editor Barry Soper says National and Labour leaders have emerged from earlier debates with neither the clear winner.
"Like the earlier debates the final Television New Zealand one tonight isn't expected to throw up any great surprises."
He continues, "Since the last one Jacinda Ardern's taken most tax changes off the table until the election in three years time, Bill English is bound to zero in on that. In particular the water tax that remains firmly on the table and has seen hundreds of farmers out in protest about it this week."
