NZCrusader:Sounddude: doubled checked with chorus for you. (another ISP's view)
CU/BB is indeed an ASAM, so ethernet backhaul options are no go. No plans to upgrade to an ISAM.
So what you getting is as good as its going to get :(
Which is not good enough in this day and age.
I wonder if the paper pushers at Chorus have any idea....
Who am I kidding....
EDIT: Someone come up with a Tui sign for Chorus. Do want.
Also @ OP I feel your pain, was in a similar position. Worst time of my life, ended up moving to the city. Problem solved.
We definitely need more lines companies so consumers can vote with their wallets.
Actually it is good enough as it meets the regulated speed requirements
