Where can I find a complete list of goods affected by NAFTA? I am looking for the list of goods that NAFTA, preferably in the format of what is subject to tariff reduction. 

I have found a few potential leads, but none seem to be exhaustive:

Here is the agreement in full (if someone is familiar, perhaps they could point me to a specific chapter?):

As highlighted by @Bkay, these linked documents are likely to rot. For future users, the keyword I was missing when searching for these documents was 'tariff schedule'. The below links to 2019 tariff schedules. I suggest that in the future a user search:

'YEAR tariff schedule COUNTRYOFINTEREST'

It may also be useful to specify the trade agreement of interest.

For USA: Harmonized Tariff Schedule 2019 Revision 2

Link: https://hts.usitc.gov/current

For Canada: Customs Tariff by Chapter (Customs Tariff 2019-1)

Link: https://www.cbsa-asfc.gc.ca/trade-commerce/tariff-tarif/2019/html/tblmod-1-eng.html

For Mexico (and all three): Mexico Import Export Codes

Chapters of interest will vary by personal use.
