Overwintering Parks in NZ

The overwintering stage in New Zealand starts in April or May. This is when swarms of Monarch butterflies form regularly to overwinter at places around the country.

On warm sunny winter days, when temperatures are over 16 degrees, you get to see a few monarchs gliding around looking for nectar nearby. Although, most of the time, during winter, Monarchs will hang in a peaceful dormant position, totally still and peaceful.

Redwood Park (2)When the Monarchs form in big clusters they are known to be in “Diapause” (resting, hanging for the winter). Many of these butterflies survive the whole winter as a dormant group, only to revive and mate in the following spring (around September/October) when the warmer weather sets in.

These Monarchs that overwinter in the trees live for about 7 – 9  months. That’s if they survive the strong frosts, storms, hail and wind conditions through the harsh winters. Whereas the Monarch butterflies that emerge during the summer months live approximately 6 to 8 weeks, once they have mated and laid all their eggs, and their job is done for the insect kingdom.

Larch Reserve CasebrookTemperature and food supply have a big influence on the size of the next summer’s monarch population. A few cold, bitter winters and heavy rain may result in a drastic reduction in the number of Monarchs and it will take a few years for numbers to re-establish again. In saying that, I’ve also witnessed hundreds of Monarchs clinging in the trees without letting go while it’s been blowing a gail! They are such small and fragile creatures who are really resilient to the winds and strong enough to cling on to the branch with their feet swinging side to side. This is why they choose to form clusters in trees in parks that have shelter from the brunt of the winds – Monarchs are are so clever!

In Auckland it’s quite common to get caterpillars all year around, although numbers are hugely reduced and far fewer sightings of monarchs occur in the winter. Whereas in the South Island we’re only able to see Monarchs in winter at the overwintering sites due to difference in temperatures. Visiting these parks with your children and family is amazing, so take a picnic and, of course, your camera. Relax while enjoying the experience above you in the trees.  

Redwood park is great for kids as the Monarchs are quite low down and my toddler even got to spot them, then quickly enjoyed kicking and crunching the leaves on the ground.

The colours in the parks are so vibrant at this time of year; I’m beginning to enjoy autumn more and more each year.  At first, you may not spot the clusters as sometimes a bunch of Monarchs will look like a branch of dead leaves just hanging in the tree. Be patient and have a good look around, also try to go on a sunny day and you’ll see them gliding around you looking for nectar in the park.

Luckily, the people of Christchurch are spoilt and have many places to spot the large clusters of monarch butterflies. I’m fortunate to have at least 6 overwintering parks within 10 minutes drive of my house to visit regularly.

Untitled design (9)Below I’ve put together an updated list for autumn 2018. I can confirm these are current overwintering spots in NZ. Please share and tell your friends, pre-schools, and family. By sharing and having easy access to this list, we can all experience this magnificent joy, and witness nature at its best. It’s absolutely amazing!

Even if you only like butterflies a little, you’ll surely love them even more once you have seen them in huge numbers.  The magical thing that I don’t understand, which astounds me, is how these Monarchs know where to go during the winter to a place where their ancestors hung the year before, without ever having been there themselves.
Ruru Lawn Cemetery in Bromley has been removed from the list. This was a popular spot for many years but we haven’t sited any this year. Anyone who can confirm sightings anywhere around the country that are not on the list below, please can you email me on monarchs@thebutterflymusketeers.com and I’ll add them in – many thanks!!

If you’d like more information regarding overwintering in New Zealand and in-depth information about the magnificent migration of millions of Monarch butterflies that travel over 2,800 miles, journeying from the northwestern United States and southern Canada to the pine and fir forests west of Mexico City in the mountains, check out my book.

    • Redwood Park – behind the tennis courts above the path APRIL – MAY ONLY.  (Hardly any as of April 2019)
    • Woodham Park – Linwood near the playground on tree. Look for the tree with the plaque on it that reads Ginko “Maidenhair” Tree. Also in the surrounding trees, including Macrocarpa tree next to it.  Wonderful there are heaps April 2019
    • Edgar Macintosh Park – The two Pine trees at the far back fence if your we entering from Condell Ave. 
    • Bishopdale Park – New location behind the Scouts Den (green building) park in the library car park.  Very cool to see so many Monarchs that were in the grass fly around me as I walked towards the tree.
    • North Canterbury – Victoria Park in Rangiora look for the conifer trees.
    • Larch Reserve – Casebrook – as you enter from Larch place they are in the large tree towards the back entrance of the park. 10 metres away from the playground. APRIL – MAY ONLY ((Hardly any as of April 2019)
    • Rawhiti Domain – North Brighton, in the Pine and Macrocarpa trees so they are not easily visible as they slot up into the needles and hide up high. Best to go on a sunny day when some maybe flying around.
    • Denton Park – Hornby – back corner near the water tank in the gum trees. 2018
  • Westpac Park – Lincoln but you have to look for them.  They are in a large Gum tree (Eucalyptus) beside the stream just beside the lower foot bridge. 2018
  • Cypress Garden Reserve – Bromley – at the back on the large evergreen trees next to the CCC sign Ruru Lawn Cemetery, drive in via Raymond Road entrance.  June 2018 I witnessed over 100 monarchs scattered between many trees feeding of Hebe and Buddleia bushes. When you walk around the reserve many just pop up of the grass in front of you and swoop around you.
  • Linwood Cemetery – If you park on McGregors Road there are many monarch feeding on the nectar bushes along side of the cemetery.  June 2018 my daughter counted 150 monarch butterflies, they were sweeping all around us and the gravestones. There are also newly planted evergreen trees that they are resting in which are short and kids are able to see close up.  The Monarchs are in diapause in many Macrocarpa & pines tress around the cemetery so its worth looking around.  (Hardly any as of yet April 2019)

  1. Kia ora
    I was wondering where the best place to take my class of five and six year olds would be to see these in Christchurch? There are a lot of options which are great but what are the best ones?
    Thank you


  2. Do you know if there are any in Ashburton? Picnicking in Ashburton Domain tomorrow for my 2 year old’s birthday and butterflies would be a cool bonus!
