New Zealand bowler Trent Boult is unlikely to be involved against England next month, with coach Gary Stead effectively ruling him out of their Test series.

The paceman turned down his central contract in August but has still appeared for the Black Caps in white-ball cricket since.

Boult is set to spend the start of 2023 in franchise cricket, with the fast bowler set to depart the Big Bash League for a stint in the inaugural ILT20 League in the United Arab Emirates.

With the competition scheduled to end only four days before New Zealand host Ben Stokes' side at Mount Maunganui for the first of two Tests, Stead does not see Boult playing a part.

"No, I wouldn't have thought so," he said. "Trent and I have had discussions.

"I think his return from the UAE would only be a day or two immediately prior. I think from a workload perspective that's out of the picture."

Stead offered a promising update on Kyle Jamieson, who has not played competitive cricket since a back injury sustained against England in June last year.

He is set to appear in the Super Smash over the next week, though the Stead could make no promises about his inclusion in the wider red-ball picture.

"We'll make a decision a little bit closer to the time around the England series, whether that is maybe a step too far, or whether it is the right time for him to play again," he said.

"He's been out of cricket for a long time now and I think it would be silly to push too quickly and set him back again with the long-term plan of what's ahead of us."
