DC-8 jets were introduced to Wellington Airport in 1972, with a 180m runway extension - to 1936m (approx. 6352ft) in total. This was still rather short for a DC-8, and special runway markings were introduced unique to Wellington.
Google Maps/Earth (I get them via gc.kls2.com) will show the actual markings, but in brief they are four sets of HORIZONTAL lines on the runway.
My questions are, what do they mean, and thus what purpose do they actually serve?

I can't remember exactly but I just checked (admittedly out of date) IFG and it made no mention of those markings. Perhaps they represent a point where there is no longer sufficient runway length remaining for large aircraft? ie commence a missed-approach/go around.

Quoting Zeke (Reply 10): They are touch down zone limitation markers, must touch down before that mark, die mainly to the winds experienced at that airport.
If they are Touch Down Limitation, this does not affect GA Aircraft. Where touching down one the 2000 foot markers (500 feet past this zone) to minimise time on the runway, as nearly all GA aircraft vacate to the Western Apron, via Whiskey 1 & 2.

Not sure, understand they have some local GA procedures. I would see no reason why not to land further down in a light aircraft when it is obvious you dont need anywhere near the full length.
