Trains:
The train system in New Zealand is great for scenic rides that show off the spectacular landscapes around the country. With over 2,565 miles of track, the train can take more time than flying. However, the scenery found along the three main train routes on the Northern Explorer, Coastal Pacific, and TranzAlpine lines covers both the North and South islands for a pleasant journey.
Flights:
Flying is the main gateway into and around New Zealand, with approximately 62 airports that connect the various islands. Flights are fast, efficient, and take much less time than driving. For example, you can hop onto a 50-minute flight between Auckland and Wellington, versus a six-hour drive. Trains can be more scenic, but flying is generally your best option when you have a specific schedule, especially when traveling far distances like Auckland to Christchurch or Wellington to Queenstown.
