You can also just not use whitespace for your field separator.  For example
with awk and sort:

vmstat -z | awk -F '[:,]' '/ITEM/ { next } /^$/ { next } // { printf "%s:\t%d\n", $1, $2 * ($4 + $5) }' | sort -t: -k 2 -n 

(This computes the total size of allocated memory (both used and free items)
for a zone and sorts the list so the biggest zones are last.)
