Not necessary for cross post.

I just come from FreeBSD. At the begining I have the same problem. I 
solved the problem by setting my first group to be operator (so that to 
shutdown) and put wheel as secondary group.
$user mod -G wheel -g operator username

This works for me, try it. I think NetBSD want wheel to be the second 
group to avoid security issues.
