Tararuas destination Maungahuka Sept 09 Wise?

Hi all Sorry if this topic has already been covered elsewhere - I get little time to read through these forums (much as I'd like to!) I'm planning a trip to Maungahuka in mid Sept and just wondered if anyone could comment on conditions at this time of year (ie., from past experience)? I'm an experienced tramper in these ranges but not to the extent that I can compass navigate and I have no desire to be in knee deep snow and white out conditions. This may seem a strange comment for someone familiar with the Tararuas! I will make all the usual weather check s pre trip but just want to get a 'weather gauge' if I can for what the tops are like - and the Tararua Peaks and the main range in particular at this time of year. Any suggestions/help/comments welcome!
