local to a national...

This would be up to the national that was absorbing the local. ZTA does give all alumnae of the local the opportunity to become Zetas. At my chapter only a small handfull did. This has to be done at the time of chapter installation. I had an alumna contact me a 10 years later, she wanted to become a Zeta since her daughter joined an NPC in college. She could not since the invitation is only "vaild" during the installation year.

Exactly.

I believe most NPC organizations do allow alumnae of absorbed locals to be initiated. Such women immediately take on alumna status. (This is currently the only form of alumna initiation that AEPhi offers.) Women who accept the invitation and are initiated hold the same status as alumnae who followed the "traditional" path of rushing and pledging and being active members during their undergraduate years. Thus, these women's daughters (and sisters, granddaughters, nieces, etc. per national policy) are considered legacies.

The only exception would be for alumnae of the local who have been initiated into other NPC sororities. Once you're initiated into one NPC sorority, you can never join another.
