You can google the flight route and add trip report to read stories from people that took that specific flight. Sites like Airliners.net or flyertalk.com should pop up. But check the date of posting as airlines tend to change routes while not always changing the flight number.
A better option is to check sites like fr24.com and flightaware.com. Here you can see the route traveled by an aircraft and see where it has touched down and for how long it was on the ground.
For now Emirates has a direct service to Auckland, EK448/EK449
