Strange, I'm in Auckland and obviously routing to Christchurch first before hopping out to the states, so my latency should be higher than you, I'm also on an ADSL 2+ profile, syncing at 19mbps. I was downloading something on Steam earlier and was pulling just over 1MB/s. Snap has gotten a little slower of late, but still seems quick.

I remember back when I was with them I used to have great speeds like that. For a couple years I could easily get > 1MB/s from my servers in the US.
One day things went from that to 30KB/s, after a few months with no resolution I left. With the large variation in results it's almost like they have different pools with very different speed profiles.
I believe any slowdowns appear to be coming from their upstream provider Telstraclear. Others ISPs which also use Telstraclear for transit have also noticed a reduction is speed to the states.
I only picked this up the other day after the ISP I work for re-balanced out some of our transit which lead to my connection preferring telstraclear routes as apposed to another transit provider. The reduction in speed was obvious, although appears to be ok now.
The techs at Snap are pretty on-to-it so i'm sure they'll know what to do if the problem does for them lie with an upstream provider
Upon getting frustrated again I called the helpdesk. I was asked to forward a series of speedtest results so their email so they can forward to their NOC team.
I'm waiting to hear back.
The guy also said interleaving on my line is off (as it was with my previous ISP) and that we could try turning it on as something to try...

Turning interleaving on will just increase your latency and have a negative effect on the max download rate you can get on a single threaded download from the US.
Leave it off.
Sounds like they are still having problem with their international carrier (Telstraclear/Reach).
I had the same speed issues with Snap since 1/2 weeks ago and it seems to be fixed since 2-3days. Hopefully this will stay this way for a long time now...
I'll start by saying that packet loss is a big big deal when it comes to download speeds, and it's frequently overlooked.
Turning off interleave will mean that you turn off most of the error correction on your ADSL. I say most, because you are taking away temporal error correction - that is, the type of error correction that protects against 'spikes' of noise on your line. (Think of the click that your home theater setup makes when you turn lights on and off.) This could lead to more packets being dropped between your ISP and you.
If packets are dropped between you and your ISP, they will need to be re-sent from where you were receiving them. If that is close to you (say, the ping to where you were downloading from is 50ms) -- the re-sent traffic will take 50ms to reach you (presuming it's not dropped again). If that is far away from you (say, the US, ~200ms) -- the re-sent traffic will take 200ms to reach you (presuming it's not dropped again).
So, turning off interleave will probably slow your international down significantly, but won't have a huge effect on your national speeds.
Most gamers have interleave off since their traffic usually comes from very close sources (<150ms), and it's more efficient to have some packets dropped and have the game's network code compensate for this (specific error correction), than to correct for this condition in the ADSL layer (general error correction).
