Mods feel free to move this if you feel the need, I put in Broadband because the cable is of most interest to me.
TL;DR the guy behind the Hawaiiki Cable and the guy behind CallPLus have teamed up to propose a massive new datacenter near InverCargill, along with a new Invercargill to Sydney cable with Christchurch/Wellington branch lines.
I've been banging the drum about a wellington/SI to Aus cable being a good idea for awhile now so I'm rather enthusiastic.. Hopefully things line up for them.
