Using env doesn't solve the problem either. There is no guarantee the "env"
program is installed under /usr/bin/env. It may as well be installed under
/usr/local/bin/env.
But every unix should have a bourne shell compatible shell located at /bin/sh.
You can use a bourne shell compatible code snippet and call zsh from it. If
PATH contains zsh than this will do the trick.
#!/bin/sh
if [ -z "$ZSH_VERSION" ]; then
## searching PATH for zsh executable
exec zsh $* < $0
## no zsh detected
exit 1
fi
## zsh should be running now. do zsh stuff
print "hello"
