How Do I Merge a Numbers Doc W/ Contact Details Into Pages To Create Maillabels?

I have a “contact list” in Numbers with people’s names and contact details, all in separate columns for firstname, lastname, zipcode, etc.
Question: I would like to create mailing labels. Can I import (mail merge) the data somehow into Pages and then format to match the label size and lay-out?
Thanks in advance. MacMost is fantastic!!
When I was still using MS Excel and MS Word, I used to be able to “import” the spread sheet data (first name, last name, etc) into the Word document to create either a maillabel document (to print individual labels) or a mail merge into a personalised newsletter. I haven’t found a way in Mac (Numbers and Pages) to achieve the same.
