It's hard to tell what the squads will be yet as the South African series will be what decides who goes and who stays, i.e if Cumming has a goodish innings in the last ODI here then plays averagely against South Africa I'd imagine he won't be going. If he plays several good innings against the Saffas then I would think the selectors would keep him on (the old saying - it's harder to get out of the NZ team than to get in it)
The only ones you can be sure are going, no matter what their form in the up-coming series will be
Fleming
Richardson
Tuffey
Styris
McCullum
Vettori (like Cairns would never be dropped unless injured I'm sure)
Cairns
Oram
Marshall
Astle & Bond if fit
I don't think McMillan has done quite enough yet to cement his place in the one-day squad at least I mean if he has a very poor next series his place would be in Jeopardy. Likewise Hart even though McCullum is sh*thouse keeper he would be a more suitable choice if Hart fails miserable with the bat and is average with the gloves. Mills, Adams, Butler, Mason etc. would all be fighting for the third genuine bowler spot along Tuffey and Bond (assuming fit)
