There are lots of other and better farewells for him on the net, including this one by his wife Anne Else on Harvey's own blog: http://stoatspring.blogspot.com/2011/01/last-post.html, but I just wanted to say a short quiet farewell too. I didn't know Harvey very well, but met him at various literary things, and more recently I've known him through his blog. He wrote a lovely review of my first poetry collection, which I always appreciated. The thing I remember him most and often for is a kowhai seedling I got at the launch for his book This Piece of Earth - if you bought the book you got a seedling. The seedling is now a smallish tree and, while I'm no longer in the habit of naming all my plants, I've always thought of that tree as 'Harvey'.
Here's a few of the other tributes:
