Thanks Henrik!
Ok I have done what you suggested and now I see the usernames in access.log
on the 2nd tier proxy... however I am consistently denied access (my IE
session brings up a login/password box)..
The 1st Tier Proxy's squid.conf
auth_param ntlm program /lib/squid/ntlm_auth
--helper-protocol=squid-2.5-ntlmssp
auth_param ntlm children 5
auth_param ntlm max_challenge_reuses 0
auth_param ntlm max_challenge_lifetime 2 minutes
cache_peer proxytier2.fqdn.co.nz parent 3128 3130 login=*
external_acl_type grouphelper %LOGIN /lib/squid/wbinfo_group.pl
acl nzproxyusers external grouphelper DOMAIN\LocalGroup
http_access deny !nzproxyusers
The 2nd Tier Proxy's squid.conf
auth_param basic program /libexec/fakeauth_auth
auth_param basic children 5
auth_param basic realm Squid Proxy Tier-2
auth_param basic credentialsttl 1 minute
acl nzproxyauth proxy_auth REQUIRED
http_access allow nzproxyauth
http_access allow proxytier1.fqdn.co.nz
Any ideas on what I have gotten wrong?
Many thanks :)
Andrew.

Then you need to set up a system where "faked" logins are used to the 2nd
tier proxy. You can set up the first proxy to log in with the same
username but a static password. See the login= cache_peer option.
This also requires reconfiguring the parent proxy to require basic
authentication and know about the static password assigned to the first
proxy.

Won't help. You can't proxy ntlm_auth due to the nature of NTLM.
