Checkout this java based utility nzip for nested zips.

Extracting and compressing nested zips can be done easily using following commands:

java -jar nzip.jar -c list -s readme.zip 

java -jar nzip.jar -c extract -s "C:\project\readme.zip" -t readme 

java -jar nzip.jar -c compress -s readme -t "C:\project\readme.zip"
