Hello BaldGorilla, and welcome to the Monastery!

I assume the line print $new_gpd_fh "$line"; is meant to be print $new_fh "$line";? With this change made, I cannot reproduce your problem.

Specifically, I created a text file, then used a hex editor to insert a null (\x00) at a suitable place in the text, and ran the script. The resulting new file has a null character in the correct place, as expected. (Confirmed both in the hex editor and in Notepad++, which displays a NUL control character.)

Are you sure that your new file contains a space character in place of the null? Or could the space you are seeing be an artefact of the way you are viewing the file contents?

Cheers,
