Colin de Grandhomme, Jeet Raval and Neil Broom are the new inclusions in New Zealand Cricket's central contracts list for the 2017-18 season. Mark Craig, Doug Bracewell and Luke Ronchi, who had announced his international retirement in June, were left out of the 21-player list.

De Grandhomme has scored 397 runs in 18 games across formats since 2016 at an average of 28.35, and has taken 26 wickets, including 6 for 41 against Pakistan on his Test debut.

Raval, who also made his Test debut against Pakistan in November last year, opened for New Zealand in each of their seven Tests in the 2016-17 home season, scoring 493 runs at an average of 44.81.

Broom played two Tests against South Africa last year, but was a more prominent figure in New Zealand's limited-overs teams. Since December 2016, Broom has hit 602 runs at an average of 43 in 15 ODIs, with four fifties and a hundred.

"Colin made a breakthrough last summer and is rated well in all three formats; Jeet's Test numbers speak for themselves, and Neil, as well as averaging 43 in ODI cricket since his recall, is also seen as viable cover for the Test team's middle-order," selector Gavin Larsen said.

In Ronchi's absence, BJ Watling was the only specialist wicketkeeper to be handed a central contract.

Central contracts list: Corey Anderson, Trent Boult, Neil Broom, Colin de Grandhomme, Martin Guptill, Matt Henry, Tom Latham, Mitchell McClenaghan, Adam Milne, Colin Munro, Henry Nicholls, James Neesham, Jeet Raval, Mitchell Santner, Ish Sodhi, Tim Southee, Ross Taylor, Neil Wagner, BJ Watling, Kane Williamson, George Worker.
