Pre-season sightings of whitebait are few and far between, despite the number of fishermen starting to amass on the riverbanks on the West Coast, where the whitebait season opens today.
"The rivers are very, very low," Department of Conservation Greymouth ranger Brad Edwards said.
"About three weeks ago, there was quite a lot of bait around."
However, since last week there had been no reported sightings.
He said a "couple" of early starters had been caught on the Grey River.
