Groupama have opened a decisive gap on the rest of the fleet in the Volvo Ocean Race as they close on Auckland as Camper struggle to find the speed to match their rivals.
The French boat are 120 miles ahead of Puma in second, with Telefonica (145 miles) and Camper (200 miles) battling for the minor placings.
Although the wind looks unstable heading into Auckland, with light winds forecast near the top of the North Island, Groupama have only 875 miles to race and could reach Auckland as early as Saturday.
Camper, who are expected to arrive mid-Sunday morning, will keep pushing but will be bitterly disappointed if they don't sail into Auckland first.
Team New Zealand boss Grant Dalton virtually demanded success on the leg but, since damaging a sail and losing ground last week, have made little headway. They have not enjoyed tight reaching conditions and had hoped for more down-wind racing and it leaves their chances of overall success looking bleak.
