Modules & VBA :: Importing New Records Into Existing Database

I have table1 in my (Access 2010) database that has exising records. I have another table2 that after I run a query, it first deletes the data in table 2, then imports new records into that table. I run the import into table 2 on a semi regular basis but have yet to copy those records into table 1.

With that said, using either a query or VB, how do I copy all the (new) records from table 2 into table 1 without altering any records that already exist in table1?

BTW, Table 1 has a main form with a subform within it
