What will New Zealand do when...?

the champion Dan Vettori calls it a day? Admittedly the guy is only 31 and would no doubt have a few years left up his sleave but who will be there to rescue them as he has done so often (current test an example and his near heroics in on the ODI's gone) over the years? Who of the current generation of cricketers in NZ coming through or on the verge of selection could be capable (or even just partially) of filling his enormous shoes?
