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.

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.

Temperature 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 gale! 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.  

Woodham 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.

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.

Anyone who can confirm new sightings anywhere around the country that is not on the list below let us know, as we believe there are so many other sites that we don’t know about as there is not enough people looking. Always look on the side of the tree that is north facing as Monarch butterflies love to bask in the sunshine all day for heat and energy. please can you email us as monarchs@thebutterflymusketeers.com and I’ll add it to the list – 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.  Plus my book is an excellent guide for raising healthy Monarch Butterflies check out my book & purchase my book here.

A BIG thank you to all the butterfly musketeers that visited and checked the sites that I couldn’t get go, to report sightings with my own eyes.  It’s great to see so many overwintering parks on the list and new additions. Whilst every endeavour has been made for this list to be correct, Monarchs have their own agenda and move from tree to tree or different locations.  I have been to the same park sometimes 3 times in a week and you never know how many you would see, as this Autumn I think the Monarchs have been confused with the mild temperatures and not began to fly to their overwintering parks for winter months.  Instead they are happily still eating nectar in our own gardens as the days have been warm.

This year we hope the metal bands will protect the Monarch Butterflies from rodents and they stay safe sleeping in the tree.  If you start noticing Monarch butterfly wings on the floor in large number please let us know as we can help, and find out whats happening.

Also I would like to thank each and every one of you that raise Monarch Butterflies each summer, continuing to sow many swan plants seeds and buy endless amounts of Swan plants.  It’s because of you who puts in so much effort and time that the Monarchs are around Christchurch in their thousands.  Well done!

  1. Visited Larch Reserve, we could only find a few strings there about five. Visited also St James Park last Friday and found nothing. We that is my daughter Nellie and myself and finding nothing, while at Redwood Park
    all of the clusters are still there. Looked again this morning, the sun was shining and a few were gliding.
    It made my day. Greta Vink

  2. 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

    • Hello Amy, where about’s are you in Christchurch and I will advise as some monarchs are lower in trees than others so be easier for kids to spot.

  3. 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!

    • Could you be my new buttefly musketeers and check it out, and let me know. They are normally in Macrocarpa trees and Evergreens, Pines trees.

  4. Hi we would love to take a group of preschoolers to see the monarchs. I checked out the trees near Pioneer and couldn’t see any myself. Is this likely to be a good place for littlies to see them?

    • Sometime the move, to another tree for a free weeks and come back. It’s hard to spot sometimes as they look like a bunch of dried up leaves.

    • Can anyone answer this, or know of any nearby? Even if you know of locations in previous years that may have been overwintering destinations could once again be a location the Monarchs have returned to a couple of years later.

  5. Have just checked out a site here in Whakatane and found Hundreds of Monarchs Overwintering

    • Hi Martie, I’m SO keen to see monarchs overwintering. Where have you seen them?

      • I’m on the Coromandel peninsula, but will happily travel for a good experience of overwintering monarchs. Ever since I read Barbara Kingsolver’s Flight Behaviour I’ve been so keen!! We raise many Monarchs here , and at the local school where I work: in fact I saw two flirty butterflies sizing each other up just today, the 27th July!! Tammy

  6. Thanks so much, I visited NZ in April 2019 and saw my first Monarchs in the Plane trees by the children’s playground in Warren Park, Whakatane. They were also nectaring on the pink Silk Floss trees nearby.

  7. Hundreds monarch s at Oamaru garden s opposite red bridge in tall trees 22may 2019

  8. I never knew of this but today was taken over to Victoria Park in Rangiora by my 8 year old daughter where we saw quite a few clusters of the Monarchs, some quite low down in a few of the trees there. What an awesome sight it is to see. We will continue to make regular visits on way home from school now.

  9. Hi, any ideas of sites on the west coast? Specifically Hokitika or Greymouth?

  10. Do you know of any wintering tree in West Auckland or Freemans Bay? What’s the advantage to the butterfly of all being together over winter and how do they know where to go? Which trees to go to?

  11. summer of 2020 – we have hatched and seen lots and lots of butterflies this time around – a lot more than last year, so here’s hoping they are on the incline (in New Zealand at least).

  12. oops I should have said we have seen the butterflies around Clarks Beach, which is south of Auckland.
