i believe there were some high-rises recently built on the east side of palisades park, in the long swamp area right on the border with fort lee. no idea if they're condos or rental apartments, though. the town didn't want them built, but a developer sued and as a result of the so-called "builder's remedy", they were forced to accept these units. not sure if all three of the proposed buildings have been completed at this time.
there are also some condos and rental units that were recently built in downtown englewood. they're not high-rises per se, but these buildings have a lot of units nonetheless and might be worth looking into. downtown englewood has improved a lot over the past few years with all of the new high-end residential and retail construction.
there were also plans to build a high-rise apartment in the swampy meadowlands section of east rutherford, right across from giants stadium of all places. i saw some billboards on rt. 3 a while back advertising this place, but as of yet nothing has been built. it's really an odd place for dense residential development, but in general builders couldn't care less about the effects on the town's services and environment so long as they make bank.
other than the towns you mentioned and the examples i cited, i can't think of any other high-rises in bergen county, especially not in the northern towns. and btw hoboken is in hudson county.
