For trip planning, think of it like this:
Nonstop flights from the mainland United States to New Zealand usually take about 13 to 18 hours.
That range helps you plan the things that actually matter:
A long haul flight is not hard so much as it is repetitive. You settle in, the cabin lights change, and suddenly your job is just small choices: water, a walk, a nap, a snack, then repeat.

Here are realistic, published ballparks for common nonstop routes.
Two quick notes that help set expectations:
You might see Chicago mentioned in older lists. The important update is that Air New Zealand says nonstop flights between Chicago and Auckland are currently paused, and they are routing travellers via other US airports instead.

Auckland is still the big one. Most international flights arrive in Auckland, which is why so many itineraries start there.
There is also a useful exception to know about if you would rather start on the South Island:
Christchurch has a seasonal direct service to San Francisco with United, which Christchurch Airport describes as the only direct connection between the South Island and the USA. Although most travellers get a domestic flight from Auckland to Queenstown.
If you are planning Queenstown, Tekapo, Aoraki Mount Cook, or the West Coast, Christchurch can be a very tidy start when the timing works.
This decision is personal, but here is the way I would frame it for most travellers, especially seniors.
Choose nonstop if:
Nonstop is rarely the cheapest, but it is often the calmest.
A layover can be the better option if:
If you do take a layover, favour the itinerary with breathing room over the tight connection that looks good on paper.

New Zealand is a long way ahead of the US clock. For example, Time and Date shows Auckland being 21 hours ahead of Los Angeles on a December date (and it shifts through the year with daylight saving).
What that means in plain English
Practical booking rule: always confirm the arrival date, not just the departure date, before you book

Auckland is a good place to treat as your “arrival buffer”, even if you do not plan to stay long. Most US travellers land here, clear border formalities, then either head into the city for a soft landing or connect onward to other New Zealand destinations.
Air New Zealand’s connection guidance is clear: if you are connecting to a domestic flight after arriving internationally, you generally need to collect your bag, clear Customs and biosecurity, then transfer your baggage to your domestic flight check-in area.
Auckland Airport provides a free terminal transfer bus that runs every 15 minutes between the international and domestic terminals.
Even when everything goes smoothly, your arrival process has a few steps. That is why many travellers, especially seniors, prefer one of these two approaches:

Entry rules can change, so check official guidance close to departure. Here are the practical basics that catch people out.
The New Zealand Electronic Travel Authority (NZeTA) is a travel authorisation used by travellers from visa waiver countries. It is valid for 2 years for travellers, and Immigration New Zealand says to allow 72 hours for processing
An NZeTA can allow stays of up to 3 months per visit for travellers who arrive under the visa waiver settings.
The New Zealand Traveller Declaration collects customs, immigration, and biosecurity information, and the earliest you can submit it is 24 hours before you start your journey to New Zealand
New Zealand takes biosecurity seriously, as this is key to protecting its iconic wildlife and nature. It is New Zealand law to declare all risk goods, and failing to declare can lead to a $400NZD instant fine (and more serious penalties in some cases).
If you are unsure about food, hiking boots, camping gear, wooden souvenirs, or anything outdoorsy, the best move is to declare it. It is faster than being pulled aside.
Here is a guide of New Zealand biosecurity laws.

If you only take one piece of advice from this article, take this: plan to arrive well, not just arrive.
On the flight
If you have medical risks, talk with your clinician before you fly. Long haul is not the time to wing it.
First 24 hours in New Zealand

If you plan to drive, make this part of your prep.
If you are not comfortable driving left on unfamiliar roads while jet lagged, build in that Auckland buffer night before you pick up a car.
