The pair were originally due to fight again in November but the bout was postponed after Povetkin, 41, contracted coronavirus and spent some time in hospital.
They were then scheduled to fight at Wembley on 6 March, but travel restrictions because of the Covid-19 pandemic prompted a further change of date and venue.
The first fight took place behind closed doors at promoter Matchroom Boxing’s headquarters in Essex, but a crowd of 500 will watch the bout in Gibraltar.
Whyte, 32, said he will be more “switched on and focused” this time after the first defeat denied him a shot at the WBC world heavyweight title.
“I could’ve taken more advantage of those knockdowns in the fourth last time but that’s heavyweight boxing – if you fight good fighters regularly, you will lose sometimes,” he added.
“You have to be ruthless and fearless – that’s how guys get up off the floor and win fights.
“I still believe I can be one of the best heavyweights of the day, if not the best out there.
“I believe I will be world champion one day, but I’ll get this done first – I’ll knock him out.”

Whyte weighed in at 17st 9lb 3oz on Friday, half a stone lighter than the first bout, while Povetkin weighed in at 16st 4lb 4oz.
Whyte has a record of 27 wins and two losses, with defeat by Povetkin last time out his first loss since being stopped by Anthony Joshua in 2015.
Povetkin, who has 36 wins and two losses, to Joshua and Wladimir Klitschko, said he has “no thoughts” about a knockout victory again.
“My goal is to be focused on the fight and show beautiful boxing, that’s it,” he told Sky Sports.
“It will be beautiful, interesting boxing. That’s what I can say.”
Povetkin has been in at least half a dozen fights now where people afterwards have said he looks a bit old, slow and heavy.
“But he keeps on winning against good fighters – a man like that is dangerous until the final bell or the referee calls a stop.
“I can’t see Whyte stopping Povetkin unless it’s in a slugfest but my gut feeling is Whyte will win and look really good doing it and that’s going to really shake-up the heavyweight division.
