convert into zip file to .dns file with powershell

HI

I am using below command to take DNS zone backup and after zone export I am moving that file to other folder
with below script.

DNSCMD /zoneexport contoso.org contoso.org.dns

Move-Item c:\windows\system32\dns\contoso.org.dns e:\dns\contoso.org.dns


Now I want to convert.dns file to zip file so that I can send it to mail for all team members.
