I recommend checking into whatever herbicide you decide to use, and find out how long it lingers, and what sort of breakdown ("daughter") products are formed. Sometimes the daughters are worse than the original product, as far as the environment is concerned.

I think there are a lot of banned herbicides in NZ, they seem to be more concerned here over what you can and can't use, they are also bringing in regulations so that you need a certificate to use them.
I can't see any organic solution working - lets face it black plastic sheeting is not exactly an organic solution (unless you can get a biodegradable one). This stuff has a very strong deep tab root which makes it drought tollerant and very difficult to dig out. Also the bloomin stuff survives being under a large rock for several months, so probably would laugh at a little bit of plastic. It really needs something heavy duty on it.
The problem is that idealy I don't want to kill off the grass - we don' t have much top soil and I don't want what we have being blown away.
Hopefully we can find a contractor who is capable.
