How to have New Zealand currency available in the GoCardless integration?

I am trying to set up integration between jotform and gocardless but when I go to choose the currency it does not allow me to choose New Zealand dollars. I have set up NZ option in gocardless and I have contacted them in relation to this same issue but they have directed me back to Jotform to solve the issue. 

I have a attached a screen shot.

Unfortunately, this is a change that needs to be performed by our back-end team, usually, currencies are not included since they are not supported by the API; however, in order to confirm this or have the change implemented, I have passed this to our second level, although we cannot provide an ETA, we will keep you updated via this thread. 

Thanks.
