Lucky you!
With anisotropic filtering set to "application controlled" within the video card control panel and activated in fsx, it looks like this:

Since this is the only airport worldwide with those dreaded blurries, I can't believe it's caused by my setup, which is quite contemporary:
AMD 4300 quad-core @ 3.8 GHz
4096 MB RAM
NVIDIA GeForce GTX 750 Ti (2 GB RAM),
1680x1050
Win7 64Bit
Seems to me like the MIP-maps of the runway textures cause those problems, as I've seen this on aircraft textures with MIP-maps as well. Easy to switch those off, but the NZQN runway textures are hard to detect...
I do love ORBX NZNI and NZSI, but this is very disappointing!

Could it possibly be something to do with the resolution you're running? I'm on 1920x1080p And yours is a lot better than what I was putting up with. Like I said earlier the cliff blended into the rwy on 23! alot of $^^&%^& words
