"Lockie, Milney and Scott are arguably the three quickest in the country and if we went down the path of adding another quick [to the test squad] the probability is it might come from there."
There is one question mark in the test group, over wicketkeeper BJ Watling who is battling to get over a niggling hip strain. He will play as a batsman for Northern Districts against Auckland in the Plunket Shield match in Hamilton starting today and has also been earmarked to play against Otago at Alexandra immediately before the test squad gather.
Handing the keeping gloves to one-day keeper-batsman Tom Latham is not likely to happen should Watling miss the Basin test.
That means Wellington's Tom Blundell - named to keep for NZ A against the tourists and a recent tourist to India with the A squad - is shaping as the player at the head of a competitive wicketkeeper-batsman group, which also includes Northern Districts' Tim Seifert.
There are three changes from the last New Zealand test team - back in late March against South Africa in Hamilton - with Boult, Southee and senior batsman Ross Taylor, who all missed that match with injuries, returning.
Black Caps squad: Kane Williamson (c), Tom Latham, Jeet Raval, Ross Taylor, Henry Nicholls, Mitchell Santner, BJ Watling, Colin de Grandhomme, Tim Southee, Matt Henry, Neil Wagner, Trent Boult (one to be added).
New Zealand A team: Martin Guptill (c), Jeet Raval, George Worker, Neil Broom, Colin Munro, Tom Bruce, Todd Astle, Tom Blundell, Scott Kuggeleijn, Adam Milne, Lockie Ferguson.
