The brother told me that the sandflies/midgies on the West Coast around Milford Sound were horrific when he was there 10yrs ago. We have a similar attraction to the little monsters (we're usually main course) and I'm a bit apprehensive about spending the holiday looking like a pox victim. 10km from where we live there is some problem around late afternoon and I spray liberal amounts of repellent over me before getting out of the car at the mate's place. They got me last week through the socks and joggers on the top of the feet, even after I'd sprayed. I reckon they'd undo my shoelaces if they could!
