Are they using the same technology for Gigatown?

Yes. It's not a problem though because only ~20% of the people in Dunedin who can get fibre has it installed, and only about half of them are on gigatown.
Correct me if I'm wrong, but back in the 2000s wasn't the CIR on ADSL somewhere in the range of 32kbps per person? Somehow that managed to work out ok, even when plans moved to full line speed. Obviously our data consumption habits have changed a lot since then, but even so the CIR on UFB seems unbelievably generous to me. I think this is one part of the UFB rollout that was done absolutely right.
allio:ADSL1 equipment in urban areas (500+ lines, ASAMs over ATM backhaul) was upgraded to ADSL2+ (ISAMs and Ethernet backhaul) around 2006-2007 with loop shortening/cabinetisation in the years following.Correct me if I'm wrong, but back in the 2000s wasn't the CIR on ADSL somewhere in the range of 32kbps per person?

Just to correct one thing - there is *no* CIR on the EIR component of a UFB plan. The only place a CIR exists is the CIR itself that is only used with correct 802.1p tagging, and only on a connection with VLAN tagging enabled as the upstream CIR can't be accessed without this.
The 32kbps imploded - that's why Chorus removed the cap with EUBA.
@BarTender: Vodafone use multicast to broadcast their content across the GPON. Then it just depends on how much capacity they want to multicast vs per subscriber unicast over the regular bitstream 2a service.
Plenty of folks know how it works. And after the last few weeks of work the GPON isn't of the greatest concern. It's a whole myriad of other issues that hang around it that concern me a whole lot more.
Can you expand on some of these concerns/issues? As this thread is educational, and I'm finding it all quite interesting.

Are there any plans at current to upgrade the OLTs to 10GPON 10Gbps. Here is a link from Huawei http://www.huawei.com/ilink/en/solutions/broader-smarter/HW_453305. This would provide quite a performance enhancement and remove the limitations of our current GPON architecture?

The trials have already started for 40 GPON http://www.lightwaveonline.com/articles/2014/03/etisalat-to-trial-40g-gpon-technology-from-huawei.html
