Do you experience a runny nose, sneezing and watering eyes but aren’t sick? You may be one of the 20% of New Zealanders who react to different pollen in the air. Take a look at our comprehensive guide to hay fever symptoms and treatments to find out more.
Hay fever is the common term used describe the body’s allergic response to grass, weed and tree pollen. Hay fever is a form of allergic rhinitis (inflammation of the nasal passage lining) known as ‘Seasonal Rhinitis – where symptoms occur at certain times of the year, for example in summer when grass pollen is released into the air.
Allergens (in this case pollen) are dispersed through the air and breathed in through the nose and mouth. When the allergen comes into contact with the sensitive lining of the nose and sinuses it triggers the body’s natural allergic response unnecessarily thinking these tiny particles are invaders.
This allergic response causes an overreaction from antibodies and the release of a chemical called histamine into the body. This causes inflammation and results in a variety of symptoms as listed below.
Pollen is a powder like substance produced by flowers, trees, weeds and grasses, it is used to fertilise plants of the same species to produce a seed. Pollen grains are very small and light and are dispersed by floating in the air, and can travel long distances. Breathing in this pollen is the cause of hay fever.
It is best to see your GP to find out if you are allergic to pollen. They will generally use the ‘prick test’ method which involves a small scratch or prick of the skin with specially prepared allergen solutions from each of the different pollen types.
If you are allergic your skin will react with varying degrees of redness, swelling or even hives – or any combination of these things. It is important to note it is the specific proteins present in these pollen that people are reacting to, allergies to flowers such as lilies or daisies is more likely due to the scent rather than pollen.
These tests will help to determine which types of pollen you react to and also how severe your reaction is. This information will aid the doctor in determining the best course of treatment for you as well as providing you with a more specific idea of which pollen you need to avoid.
Each person’s allergic response to allergens can differ but those who suffer from hay fever are usually subject to the following symptoms when exposed to pollen.

The term hay fever and Allergic Rhinitis are often used interchangeably however there is a distinction made within this classification of Rhinitis. Allergic Rhinitis is officially described as “an inappropriate immune system response to an allergen” the most common forms of allergens are dust mites, pet dander, pollen and mould. Allergic rhinitis can be categorised into two sub categories;
Because hay fever is considered seasonal, it is more a type of Allergic Rhinitis and should be referred to as Seasonal Rhinitis in most cases.
Hay fever and colds can be easy to confuse because they both result in similar symptoms initially. Both may present with sneezing, runny nose and even a cough. So how can you tell the difference?
Timing is a key factor, colds are more prevalent during the winter months while hay fever is most often encountered during the warmer months. Hay fever symptoms are almost immediately evident and occur with a few minutes of coming into contact with the airborne allergen, while colds tend to be contracted through touch or coughs and sneezes several days after contact. As well as timing there are two key differences between the two conditions;
The length of the pollen season in New Zealand depends on where you live around the country and the specific species of plants/trees you are allergic to but here is a general guide to the pollens and when they are released. Officially the pollen season in New Zealand lasts around 34 weeks (however there are different pollen released at all times of the year), and the timing of the official pollen season does vary each calendar year.
Pines, Macrocarpa and Wattle trees kick off the pollen season in July and August, with other trees such as Oak, Poplar, Ash, Elm, Alder and Birch joining in over August and into September.
Grass pollen make an entrance from around October through to February, this includes the pollen from various species of grass with the top three being Ryegrass, Timothy and Cocksfoot grass.
Privet and members of the Composite family of weeds add to the pollen load throughout January and February including weeds such as plantains, sorrels and nettles.
Fungal spores can also be a factor for many and are most prominent in February and March but are released year round. For more detailed information on NZ’s pollen calendar see Allergy NZ’s link here.
For an indication of what pollen levels are in your area, local weather website Metservice NZ provide a simple pollen forecast service over the spring, summer, autumn seasons. A rating of ‘low’, ‘moderate’ or ‘high’ is given for each city as well as an indication of the types of pollen likely to be encountered.
