Hay Fever in New Zealand – Should You Worry?

If you’re reading this blog, you’re probably like me — a bit worried about hay fever in New Zealand. The seasons there are reversed compared to those in the Netherlands. So, is it necessary to bring allergy medication on your New Zealand trip? I’ve got some encouraging news for you: personally, I had no hay fever symptoms at all in New Zealand! But don’t celebrate too soon — especially in spring and early summer, you might still experience some symptoms. And you’re not alone: about 20% of New Zealand’s population suffers from hay fever.

Where in New Zealand can you get hay fever?

In New Zealand, the pollen season starts in the north of the North Island and gradually moves south across the South Island.

Usually, trees are the first to pollinate as the weather warms toward the end of winter or early spring (sometimes as early as July). However, this can vary from year to year and is likely influenced by climate change. If you’re visiting during the popular months of November and December, you probably don’t need to worry too much about tree pollen, since this period usually doesn’t last long.

Acacia trees are often the main culprits when it comes to pollen allergies, along with silver birches and oaks. The tree pollen season begins in August and continues through October.

Hay fever in New Zealand: mainly caused by grasses

The grass pollen season lasts several months, from August or September through March. Pollen levels vary by region and, of course, depend on the weather. Pollen is released on warm, dry, windy days, while rain washes it out of the air. If you have frequent rainy days — which are common in New Zealand — you’ll likely have little trouble.

Because of its remote location, New Zealand has fewer plant and tree species than many other countries. This means there’s a smaller variety of allergens, which can actually reduce the likelihood of allergic reactions.

Introduction of exotic plants

The introduction of exotic plants to New Zealand has led to an increase in environmental allergens. Some of these imported species produce large amounts of pollen, which can worsen hay fever symptoms. Although New Zealand enforces strict protection of its native flora, introduced plants that bloom abundantly can still affect allergy sufferers.

Hay fever tip for New Zealand: take your allergy meds just in case

Do you suffer from hay fever in your home country? Then definitely bring your tablets or nasal spray. People have different experiences in New Zealand — some suddenly have no symptoms at all, while others still do. It’s best to be prepared. Personally, I didn’t have any issues during my trip (November – December), but I still brought medication just in case. Prefer to take your chances and skip packing allergy meds? Don’t worry — I even saw hay fever product ads on local TV (NZ1). Local pharmacies will be happy to help you if needed.
