What are some essential packing tips for traveling to New Zealand, considering the availability of goods and services in the country?

Pack lightly with versatility in mind and take only the bare necessities. Consider multi-purpose clothing and remember that in New Zealand, you can easily purchase any essential items you may have left behind. Try "cross-packing" with a companion and roll your clothes instead of folding to save space and prevent creasing. Pack thoughtfully and make your holiday more comfortable by travelling with less unnecessary luggage.
