Official wording
(iii) Be solely entering and staying on Guam or the CNMI for a period not to exceed forty-five days; … (v) On or after November 29, 2024, receive electronic travel authorization pursuant to paragraph (q)(9) of this section; … Nationals of the following countries are eligible to participate in the Guam-CNMI Visa Waiver Program for purposes of admission to both Guam and the CNMI: Australia, Brunei, Japan, Malaysia, Nauru, New Zealand, Papua New Guinea, Republic of Korea, Singapore, and the United Kingdom.
Aevamo’s reading
8 CFR 212.1 is the regulation that imposes the visa and documentary requirement on arriving nonimmigrant aliens (chapeau) and that creates and specifies the Visa Waiver Program exemption (i), the Guam-CNMI Visa Waiver Program (paragraph (q)) and the CNMI EVS-TAP (paragraph (r)); it implements INA 212 and Pub. L. 110-229 and is the operative instrument for who may enter Guam and the CNMI without a visa.
The regulation lists the countries eligible for the Guam-CNMI Visa Waiver Program for admission to both Guam and the CNMI, limits the stay to forty-five days, and requires an electronic travel authorization from CBP on or after November 29, 2024, so each listed national must obtain that authorization before travel and may stay up to 45 days.

What this answer covers Limits & assumptions
Work and residence rights are separate from this check. This is the entry rule and the length of stay the instrument grants. It is not a decision about you: the officer at the border decides admission, and we do not evaluate the purpose of your trip, your passport's remaining validity, an onward ticket, funds, insurance or health requirements.
The rule is one instrument covering 2 places, so this answer is the same for Northern Mariana Islands .
