Let me clarify in simple terms

Enable promotes 100Mb/s for residential users - here;

UltrafastFibre promotes 100Mb/s for residential users - here;

Chorus/CFH calls the 30 and 100Mb/s new services "bandwidth profiles" in their Bitstream 2 Service http://www.chorus.co.nz/file/24162/chorus-ufb-services-agreement-service-description-for-bitstream-2.pdf

I cannot find at any stage an LFC explaining that the speed you will actually get is subject to the limitations of Level 3 over Level 2.

As stated earlier, Enable have replaced their offering with a higher Level 2 speed to achieve the advertised speeds at Level 3. TrueNet have measured that change and reported success.
