"It's a really good opportunity for all three," national selection convener Gavin Larsen said.
"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 various injuries, returning.
Martin Guptill, angling to force his way back into the test team, will press on with his switch to the middle order, captains NZ A and will bat at No4, with hard-hitting Colin Munro at No5.
