While the unavailable list numbered three, selectors have added five new players to the 13-strong Warren Marr-coached squad.
Wanganui Collegiate players Angus Dinwiddie, Connor O'Leary, wicketkeeper Matt Simes and Tre Bidois and Thomas Walshe from Palmerston North Boys High have been named in the squad to take on Manawatu in Napier on Friday.
"We will obviously miss Craig, Nick and Akash who are all genuine players with much to offer, the intention was always to blood these new young guys, they have all earned their spots in the squad," Lock said.
"We will be competitive and while it is our first outing as a representative team, everyone else is in the same boat. The weather has been nasty this week in Hawkes Bay and it will be a damp track, but the forecast is good for the weekend - again everyone is in the same boat.
"Manawatu will be tough as one of the top few teams, but we'll be giving it our best over the three day tournament," Lock said.
The squad is: Ben Smith, Thomas Walshe, Greg Smith, John McIlraith, Mark Fraser, Simon Badger (C), Bryce Grant, Matt Simes, Trey Bidois, Ross Kinnerley, Connor O'Leary, Angus Dinwiddie, Chris Stewart.
