Which Routes Only Require Quads/trijets?

More and more tri-jets and quads are being replaced by more efficient twins such as the 777 , A330, 787, A350 etc. especially since ETOPS allows these planes to fly routes which years ago were not allowed by twins. Are there any current routes that still require a quad or tri-jet because of the distance between land?

Depends what you mean by "require". On AKL-EZE they could dogleg and stay twin-engine-legal, but I'm too lazy right now to see how much distance that would add. Anyone flying from S Africa to S America would have a fair detour to stay within range of Ascension, and if Ascension isn't available...

With the FAA recently relaxing ETOPS rules most of the world has been opened up to twin engine aircraft. The South Pole is still off limits, but with the proper aircraft equipment and safety record airlines can fly a twin on nearly every viable commercial route you could imagine.

Essentially routes that require more than ETOPS180 are confined to Aus.and NZ to South America and to South Africa . If any carrier was certified to ETOPS330 it would be a non-issue, or the fly-around distance would not be significant. However I don't believe there are any carriers with better than ETOPS180 that operate in that part of the world.
There is a part of the LAX-PPT route that exceeds ETOPS180 but when NZ flew that with the 767 they flew around the limit. It added something like 200nm to the trip.
If the new standard adopted by the FAA in the U.S. is adopted by regulators in other countries there will be a list of conditions that will apply to aircraft irrespective of whether they have two or twenty engines. Some have to do with the route that the flight is flying. This is particularly so with trans-polar flights.

And whenever St Helena Island airport is built, that one surely won't be able to handle anything bigger than B737/A320t.
So any route between JNB/CPT/MPM and GIG/GRU/EZE will most likely require B747/A340/A380(!) unless flying a longer ETOPS180-friendly route.

IIRC, Air Tahiti Nui specifically purchased the A340 to avoid ANY ETOPS issues.

It has been discussed here in the past that AA, if it had the aircraft to do it (777) would make a great deal doing a MIA-JNB-CPT-MIA route; however, the CPT-MIA route is one that would require 180 minutes ETOPS:

MIA-CPT 138 and 180 minutes ETOPS shading
