The Rockefeller/Javits coalition and the James Buckley presence made a significant difference as well.  Nixon won NY State by the largest plurality in 1972 (passing California and Texas)-almost 60 percent of the vote.

Historically Democratic demographics who disliked the upheaval of the late 1960s and early 1970s.

Also Nixon governed as centre-left on economics which meant made it easier for white urban/ethnics to switch over. Unlike say 1984 where Reagan's economic rightwing policies couldn't turn out as much of those 1972 Nixon voters.

Likely by 1984, most of those Nixon voters left NYC to other places.  The population of NYC took a staggering drop in the 1970s.
