G'day Ken, John et al. I post this on the general list because denudation rates may also be of interest to others. You may find I.E. Whitehouse (1988) Geomorphology of the central Southern Alps, New Zealand: the interaction of plate collision and atmospheric circulation. Zeitschrifft fuer Geomorphologie N.F. 69: 105-116 of interest. Note - the relative plate tectonic rate cited in this paper is possibly a bit high (45 mm/yr) and later estimates put it at about 37 mm/yr (DeMets et al. 1990). The tectonic uplift rates may be ok though. (I'm not sure about the exact title of the publication, its only abbreviated on my copy Z. Geomorph. N.F. Let me know if you can't get hold of the journal.) Also denudation rates have been estimated from fission track analysis and this may be particularly relevant to your interest Kamp & Tippett (1993) Dynamics of Pacific Plate crust in the South Island (New Zealand) . . . J Geophys Research 98: 16105-16118 and Tippett & Kamp (1993) Fission track analysis of late Cenozoic vertical kinematics . . . J Geophys Research 98: 16119-16148 Note that there is strong disagreement between some parties in NZ re the geological reality of these and related studies!
