Why don't they just (like a lot of other people do), Advertise their
Auckland networks via APE only and their Wellington Networks
via WIX only.
Then they wouldn't be providing transit down the country.
Advertising the Entire Clear Network via APE and the Entire

The use of BGP communities would help solve their problems regarding routing ingress and
Pity it isn't more widely used.....
Transits can be filtered by community tag within an AS, and most major vendors support
using bgp communities in this way
