NZ Great Walks...

Hi all,
Im planning a trip to NZ south island this coming dec/jan. The reason for the trip is to complete a mountain course based out of Mt Cook but im very much considering doing a few other walks while im in NZ.
Ive been looking through a book i have of the NZ Great Walks and i think ive narrowed the list to 2 for this trip. Routeburn & Kepler.
If some people could share their experiences or thoughts on these two walks (or any other better ones) that would be awesome. Also, is the dec/jan period fairly reliable weather wise? Im hoping soo for the sake of the mountaineering trip, but is this an enjoyable time of year to be hiking?
Thoughts and experiences greatly appreciated.
Hutchie.
