DOC do fuck all 1080, it's all AHB and your regional council. Both need to cover a percentage of the cost, so if one says no the other, no matter how keen cannot do the application.
You are dead right that 1080 is not going away too. If you want influence with added repellant have your local branch of NZDA put in a submission for it to be used, or better still get off your arse and do one yourself.
The repellant is a blood product that is sprayed on immediately before loading in the hopper. Th issue is the application of the repellant to the bait as it is time consuming. If someone was to create a better application system then it may be easier to sell to the AHB?
If you're really keen you can also pay yourself the difference!
