Yes, it does rain on the West Coast, but not as much as you might think! Other places in New Zealand are a lot wetter - they're just better at hiding it! For example, in 2004 Hokitika got 1,964 hours of sunshine and Greymouth 1,980; both a good measure ahead of Auckland's 1,825 hours.
A few more tips that you may not know about are:
West Coast winters consist of mild temperatures, rarely any frosts and often weeks in a row of near perfect sunshine.
Summers on the West Coast can get so hot the only place to be is a lake or river.
In the north, around Karamea, the climate borders on subtropical much of the year, evidenced by lush groves of nikau palms and thriving subtropical plantings.
During winter months the alpine passes of Arthurs and Haast can be icy and do periodically get snow. For further information please visit the NZ Transpost Agency website .
