Do you need an onward ticket for Mexico?
No published rule found
No retrievable Mexican rule states a return-ticket requirement, and none states that there is no requirement. Treat this as unevidenced, not as settled.
No public rule was found. The absence of a published rule is not a guarantee of entry, and we will not guess in either direction.

What the rule actually says
The US State Department's Mexico entry section is unusually detailed and never mentions a return or onward ticket. That is suggestive, and it is not the same as a Mexican rule saying so.
Ley de Migración Article 37 could not be retrieved — every gob.mx route returned a bot challenge — so the statutory position is genuinely unknown to us.
The honest conclusion is narrow: not evidenced, not disproved. We will not tell you Mexico requires a return ticket, and we will not tell you it does not.
Absence of a published rule is not a guarantee of entry. An officer's assessment of your plans is a separate matter from whether a ticket rule exists.
Who checks
Nothing verifiable. No Mexican page describes a ticket check, and airline behaviour cannot be verified from outside the industry.
A note on airline enforcement, because almost every page on this subject states it as fact: airlines screen these rules through IATA Timatic, a paid business product with no public interface. Nobody outside the industry can check what it says for a given route on a given day. New Zealand is the only authority in this set whose own published text names the check-in desk.
