Was having some fun with casting a small(12cm) popper around local estuary flats, got a couple of follows though not sure of wether it was kahawai, or trout. Whilst i got two "grabs" nothing connected, don't think white with red head a go'er, put other colours might, anybody know of 8-12cm poppers available in nz that do work on kahawai? Keen to give this ago with whitebait season about to start.

These are the two types i use and have had good success

Sometime KY will take to anything.....other times they can be real fussy.
And I think more often than not the size of the lure is often the critical factor....on that day.

River to sea bubble pop poppers, they come in a good smaller size for kahawai, are relatively cheap, cast a mile and are pretty well built.

I've had good luck using small stick baits to target kahawai. Have had them climbing over each other to get the lure at times.
