Jet lag plan
Waitangi is 5.199999999999999 hours behind Mexico City. You're traveling west — the easier direction. Your body delays its clock.
About 10,538 km southwest · approximately 13.1-hour non-stop flight · an ultra-long-haul flight.
The route from Mexico City, Mexico to Waitangi, New Zealand covers roughly 10,538 kilometres in a southwest direction. At standard jet cruise speed plus a one-hour allowance for taxi, climb, and descent, a non-stop flight takes about 13.1 hours. This route crosses the equator. The destination's season is reversed relative to the origin, which can amplify the perceived disorientation of jet lag — your body lands not just in a different clock but in a different daylight regime.
Mexico City is in the tropics, so day length varies only slightly across the year. Light cues for the circadian system stay strong year-round. Waitangi is in the temperate zone. Day length varies by four to six hours between summer and winter, so the season of your trip materially affects available morning and evening light.
Standard 09:00–18:00 working hours at both ends of this route overlap by approximately 3.8 hours. In Mexico City that window runs 14:15 to 18:00; in Waitangi it is 09:00 to 12:45. This is the realistic window for live meetings, customer calls, or pair work without forcing either end out of normal hours.
Only one of the two cities observes daylight saving time, so the offset between them shifts by one hour twice a year. If you have recurring meetings on this route, double-check the local time around the DST transitions (March and October/November in the northern hemisphere).
If you are a lark (morning type): Westward travel is the easier direction and larks usually feel close to baseline within 3 days. The risk for larks is overshooting: stay up later than you feel like at the destination for the first two nights to avoid waking before local sunrise.
If you are a night owl (evening type): Westward travel suits owls because the body prefers delaying over advancing. A 5.25-hour westward shift typically clears in 3 days. Stay outside in the evening light at the destination and avoid early-morning bright light for the first three days.

Waitangi is currently 5.199999999999999 hours behind Mexico City. Only one of the two cities observes daylight saving time, so the offset between them shifts by one hour twice a year. If you have recurring meetings on this route, double-check the local time around the DST transitions (March and October/November in the northern hemisphere).
Westward travel — which this route is — is the easier direction. Your body delays its clock, which is closer to its natural tendency. Most travellers clear a 5.199999999999999-hour westward shift in 4 days.
For a 5.199999999999999-hour shift, 0.3 to 0.5 mg of melatonin taken three to five hours before target bedtime at the destination is the dose supported by the Cochrane review. Higher doses (3–5 mg) do not advance phase better and increase morning grogginess. Start one day before departure.
Yes — for shifts of four hours or more, shifting bedtime and wake time by one hour per day, starting three days before departure, materially reduces post-arrival jet lag.
Owls (evening types) recover faster on westward routes because the body prefers delaying over advancing. Larks may overshoot — they should stay up later than they feel like at the destination for the first two nights.
