Daniel Vettori will be recalled if match fit for the second cricket test against England.
Bruce Martin's calf muscle injury has seen him ruled out of the tour.
Vettori, a veteran of three previous England tours, arrives in London today and is scheduled to train with the team as soon as he has recovered from his flight.
New Zealand coach Mike Hesson said Vettori would be assessed to see whether the practice bowling he has had with the Royal Challengers Bangalore in the Indian Premier League has him prepared to play five days of cricket.
"He's come over 24 hours early to let us have a look at him," Hesson said. We won't be pushing Dan but we'd love to have him."
