During package download the following errors were found in the Aliris Agent logs, while none were seen on the server side (NS/Package Server) on the IIS logs.
Thus access on NS/Package Server to the package was not a problem, and testing downloading each file within the package also was possible.
HTTP Request Failed: The system cannot find the path specified. (-2147024893)]
Download Package failed: HTTP Request Failed: The system cannot find the path specified. (-2147024893)]

Others should exhibit issue in a similar fashion, it's not NS/Agent related
When looking through the package - and enabling viewing system files and folders, the package structure contained subfolders of the DFS file-system.
The name of this folder was FfsrPrivate\.......
The directory and path structure created by this including a file within the Staging folders of this substructure created a filepath that exceeded 255 characters when combined with the packag download directory within the Altiris Agent\Software Delivery subfolders. Thus the Agent was not able to download the file successfully.
The path error may also have been specifically tied to the package having an alternate download path. Thus first we would download the package into the Altiris Agent\Software Delivery structure - which was failing, then to copy it out to the alternate download path. As there was a breakdown in this, due to the filepath limitation (imposed by Windows) the download was failing.
The resolution for this, is to change the way the package folders are used/mapped in relation to the DFS shares.
When a package folder is used, make sure it does -not- include the DfsrPrivate folder structure. I.e. make the DFSroot contain the individual package folders and then use these for distribution, rather than distributing the root DFS share.
Verification of this can be done by creating the full package download path within the Altiris Agent folders, when this has been done attempting to download the file from the NS/package server to the created directory stucture. If this fails and the total path and filename exceeds 255 characters, this is identified.
