England's senior fast bowler had a fierce wind to contend with for the majority of his 37 over spell in Wellington, raising concerns over his heel and back problems.
Anderson is prepared for one last push for the match - which begins on Thursday evening UK time - as the tourists bid to white wash New Zealand with series victories in all formats of the game.
"I feel ok," he said. "The rain probably helped in the end, getting an extra day off. It gave my body an extra bit of rest. So I hope, come Friday, my body will be ready to go five days again.
"When you've got just one test left, you always manage to find something a little bit extra in the tank - knowing we have got a few weeks off when we get home.
"If we manage to come away with a win, it'd be a fantastic winter for English cricket throughout all forms of the game."
England are expected to name an unchanged team, with the only possible vulnerability being Monty Panesar who took just one wicket in Wellington.
England could opt to go with off-spinner James Tredwell - whose last and only Test until now for England came three years ago in Bangladesh - or they could boycott both spinners for an all-pace attack giving Warwickshire's Chris Woakes his debut.
However, indications are that Panesar will keep his place for the match, which will be played on a drop-in pitch.
"We want to win the series and will be looking at it as a very important game," Anderson added.
"There's a lot of pressure around the game, and we'll have to play very well to compete with New Zealand."
Anderson, five wickets away from becoming only the fourth Englishman to take 300 in Tests, has taken only seven in this series so far and will be looking to improve in order to help England to a 1-0 series victory.
