Thanks Tom, I see what it does, runs a small script which puts this
in /var/run

echo "*** $(eval_gettext "System restart required") ***"
> /var/run/reboot-required
echo "$DPKG_MAINTSCRIPT_PACKAGE" >> /var/run/reboot-required.pkgs

Hmm, wonder what would break if I just removed the script link in 
/etc/kernel/postinst.d/update-notifier and the actual script
in /usr/share/update-notifier probably break the system or maybe it
would be regenerated. I wouldn't actually remove it anyway just move to
another folder within the main folder it's in now.
