Dean Brownlie, Doug Bracewell, Andrew Ellis, Tarun Nethula and Kruger van Wyk have been offered central contracts by new Zealand Cricket for the first time this year.
NZC today announced the 20 players offered a contract for the year from August 1.
Wellington all-rounder James Franklin has regained a central contract after missing out last year but test paceman Mark Gillespie is a notable omission.
Players from last year's list who are not contracted for 2012-13 include Hamish Bennett, Neil Broom, Andy McKay, Jesse Ryder, Luke Woodcock and Reece Young.
A set criteria is used to rank players across all three forms of the game with test cricket receiving twice the weighting of one-dayers and Twenty20 internationals; the players with the highest aggregate scores are then offered NZC contracts.
