I get Sydney because that is one of the only places that is approximately 30ms away. The details on what the traceroute's actually had in them are fuzzed away by the reporter, so you can't rely on them to say anything in particular.
Anycast nodes switching about could look a whole lot like the latency just going up to the uninitiated. Most internet providers don't actually have a huge say in which anycast node for a service gets chosen by their network unless they actually have a local node in their own network.
To address the issue in the article, I expect that if Chorus / Telecom received a request to tap your connection you will never know that they have tapped it. The dark fibre circuits we have through them are provisioned on day one with an optical tap that is configured to direct a small percentage of the light to any gear that they might one day connect to it. The latency would be completely unaffected.
What makes more sense given the story is that Dotcom was on a fast fibre tail using a service that was actually in Sydney somewhere ( ~30ms away ) and for whatever reason this service switched to a node in the middle of the USA which could be 180ms away. Nothing there to do with taps or government conspiracies. They may well have been tapping his circuit as well, but the latency won't be anything to do with it. Even if they did have to divert his connection through some GCSB site, the latency would not be as high as 180ms.
As far as ping times to perth, from the same box in skytower:

I've got my own access card for Level 47 and 48 of Sky tower, I'm aware of exactly what it is and why we decided to buy co-location space up there.
Our connection from skytower has to go a way across town before it hits the southern cross landing station, so the best case latency across southern cross is a bit lower again.
My point earlier on was that you can get anywhere return trip in New Zealand on a fibre circuit in under 35ms. Add the 24ms to get across to Australia or the 120ms to get to San Jose and you still don't get to 180ms unless you are using ADSL2+ or cable. Our POP in Christchurch is 20ms from Skytower in Auckland.
I get 24ms between a host in our network physically in Skytower in Auckland and a host in a Vocus datacenter in Sydney.

200 is totally awful! How much of that is made up by the last mile latency?
At the place I work, I would accept as a fault any report from a customer of latency of 200ms to anywhere physically in New Zealand ( aside from end customer tail latency ). Most ISP's in New Zealand peer at either WIX or APE or both and we pay extortionate rates for paid peering with Telecom and TelstraClear to handle the two exceptions to that rule.
The worst case for us is that we have an end customer in Christchurch that is talking to an end customer in Christchurch of an ISP that only peers with us in Auckland. Even that only means about 40ms worst case plus the latency of the tail circuits.
I don't know how to say it better than I did in the post you were replying to. I'll try, but perhaps you should read it again.
You can stop almost everything you don't want coming in with a non-stateful static ACL on the upstream router or something like a 3750 switch. The web server or reverse proxy or whatever you have then only has to handle traffic destined for port 80 ( and perhaps ssh from a couple of IP's ). A switch or a router can run that ACL in hardware at the line rate of the port without operating a state table at all, and it doesn't give the attacker a new easy way of taking your site out.
Theres no reason why the host can't have local firewalling too, but it is pretty well irrelevant at that point.
Well hopefully you aren't going to be consulting on anything important that gets deployed.
A stateless ACL on a switch or router that does it in a hardware path will do just fine dropping packets destined for unintended services, and it won't act as an additional attack vector.
A firewall in front of a server farm is a 'layer' that only does harm, and does not do any good.
