Retrieve contactGroups on GET request for all contacts
As far as I can tell you can't get contactGroups when doing a GET request for all contacts. You can only retrieve them when requesting a singular contact.

By specifying the optional ‘page’ parameter on GET Contacts, additional elements are returned, including any groups to which the contact belongs: http://developer.xero.com/documentation/api/contacts/#GET
