Several years ago Countdown used to sell 100g packs of (Indonesian or Malaysian - I can't quite remember which) whitebait, which I found to be almost as good as stuff from the South Island. Another good thing is these packs were only $10, which to me was pretty good value.
I haven't seen this whitebait at the supermarket for some time now, and the cheapest I have found is 100g for $35!
Has anyone found cheaper whitebait anywhere outside the South Island, or am I basically stuck?
