I just checked on my modem status page to try and see why my connection was so slow, and this is what I saw...

DSL Status:Connected
DSL Modulation Mode:MultiMode
DSL Path Mode:Interleaved
Downstream Rate:519 kbps
Upstream Rate:764 kbps
Downstream Margin:1 db
Upstream Margin:12 db
Downstream Line Attenuation:61 db
Upstream Line Attenuation:15.5 db
Downstream Transmit Power:12 db
Upstream Transmit Power:18 db

Now I know that I'm 6km from the exchange, but in the past I've been getting at least 2500kbps upstream!
It's a shame that I'm probably one of the 5% that will never get anything better in my lifetime...

61dB will do it, dont forget the upstream traffic is at the lower end of the DSL spectrum, therefore less impacted on by line length compared to downstream. Have you changed something in your house wiring, or maybe recent bad weather has caused a line issue, noticed anything odd on the voice side lately?

Obviously at this distance things can never be flash but have you tried to do a full isolation (ie connect at the demarc with all other house wiring disconnected) to see what you can ring out of it.

As Cyril said you must have some poor wiring inside your house or water has gone into your line outside that is affecting your line speed.

If you live out in the middle of nowhere you may be getting upgraded under the RBI.

Telco2 have done a reasonable RBI lookup tool here which lists the times and : http://www.telco2.co.nz/rbicabinets.html

Otherwise you may need to log a call with the broadband support desk on 0800 225 598 and get them ot log a call with Chorus to someone out to check your line.

Thanks for the replies - My router is plugged directly into the splitter, which is plugged in to the demarcation. The fax is plugged in to the other side of the splitter, and the cordless is plugged in to that.
I think I'll try replacing the splitter, then I might get telecom to check the line to the road!
I've had a look at the cabinet plans before - there is still nothing closer to me on the plan!
