The Black Caps became the first team ever to come from behind to a Test series in England following a 160-run victory at Trent Bridge which followed a 253-run success at the Oval.

Latham said after the victory at Trent Bridge: "I've said it before, when you start the series, you obviously set out to be in this position.
"What I'm most proud about of this group is the way that they're able just to stick to the things that we wanted to do well, be really clear in terms of how we wanted to operate.
"Sometimes the results don't fall your way, sometimes they do, but we're fortunate enough that we're able to, I guess, be brave enough for long enough, and stick in there for those key moments and end up on the right side, which is certainly really pleasing."
