I don't think that we should drop "Piggy" Styris, he adds so much more to the team than just batting and bowling.. with the retirement of Cairns who will take over the mantle of team stud? I mean lets be fair Pig would have to be one of the most attractive cricketers in the world, up there with Murali and Gillespie.
But in all seriousness, and this is a serious situation for NZ, we can't abandon Scotty on the basis of a couple of bad tests versus Aussie in Aussie. After all, such good players as Rahul Dravid failed on their first trips to Aussie. And yes I believe he does have the technique to bat 4 in test cricket, he just happens to be a nervous starter, but he plays shots off both the front and back foot and normally murders spinners.
Astle is a class act and hopefully will quit ODI's to prolong his test career rather than the other way around.
Richardson has to be reviewed after SL series, Papps will slot in there long term.
McMillan (he'll be back) and Marshall are both good prospects to bat 6 in the future, but not immediately.
Oram = enough said, technique power everything. Useful stock bowler but shouldn't be much more.
Fleming = elegant strokemaker.
McCullum = NZ's brightest star, robbed by two shocking decisions at Brisbane. Has not only the technique, but the temperament and intensity required to make big runs in test cricket - against the best too. Watch out for this guy to be one of the great keeper/batsman of all time. Remember he's only 23! He'll break all sorts of records. Don't be surprised if he makes big runs today.
Martin = if he can't develop an outswinger quickly he will struggle on flat pitches
Butler = Quicker than any kiwis bar Bondy, should let him loose soon.
Bond = if he ever comes back its a bonus
Tuffey = the rock the NZ attack has been lacking, a strike bowler who keeps the runs down, he also fields superbly in the outfield and is a really handy lower order batsman.
Vettori = getting back to his best, his test average will continue to head towards the low 30's which is good considering he bowls on a lot of greentops at home. batting continues to improve, is now almost a genuine allrounder. needs to get his arm ball swinging more.
Wiseman = could be useful over the next couple of years. still lacks variations, but is a more than useful batsman.
Mills = can bowl quicker than he did in Brisbane, needs to work on fitness. Good batsman.
Adams = engima, can bat bowl and field and had a great debut in test versus england but fell apart at WC 2003. can bowl with good pace and movement and hits like a kicking horse, have to get him back in the frame somehow.
So thats where we stand in NZ, I think if we can get some of our key bowlers (Tuffey, Butler, Bond???) back in play then we will win matches again.
+ we need a quality performer like Agarkar.
