Pace pair James Anderson and Ryan Sidebottom were the main inflictors of damage in the innings win at Trent Bridge, which sealed a 2-0 success.

"As soon as we were bowling it was cloudy and very damp," admitted Vaughan. "But they were still putting the ball in the right areas and showing a lot of skill."

Man-of-the-match Anderson's nine wickets took his tally for the campaign to 19 while left-armer Sidebottom finished with 16.

That pair have certainly had the measure of a young Black Caps side but can anticipate working up a greater sweat against South Africa later this summer.

Presented with perfect conditions after England stacked up 364, Anderson sent the New Zealanders tumbling to 123 all out in the first innings and Sidebottom's devastating fourth-morning spell reaped four victims to wrap up the second.

"It is the skill element that is exciting because, if you can swing the ball conventionally, when it starts getting dry and flat you can swing it the reverse side as well," he added.

"Later in the summer we are going to be tested to the max as a team and that will be the ultimate test of where we are.

"We have won 2-0 against a decent New Zealand team but there are still areas that we can improve and it's important that we do that."
