Applications :: Converting OpenOffice File To Pages Or Word?

One of my editors had starting using OpenOffice and when he sends files to me they arrive in a zip that, when opened has some games and other things and one png file that is a thumbnail of the document, very tiny.

Is there a converter for OpenOffice docs that will open them in Pages (my preference) or Word ?

Any familiar with OpenOffice? Is it necessary to receive a zip file every time from him? He's technically inept and perhaps I can just tell him how to export the proper file.
