This seminar will give an overview of some of the work being undertaken at NIWA regarding extreme weather events, the impacts they have on New Zealand, to what extent they can be attributed to human climate influence and how we might expect them to play out in the future.


  • Dáithí Stone is a climate scientist with a particular interest in documenting how and why the climate has changed and is currently changing, and the influence these changes have had on natural, managed, and human systems. He has worked in Canada, Latvia, South Africa, the U.K., and the U.S., but now finds himself in Aotearoa New Zealand. Dáithí Stone étudie le climat, particulierement la documentation des changements climatiques et leurs causes dans le passé et le présent, ainsi que leurs effets sur les systemes naturels and humains. Il a travaillé au Canada, la Lettonie, l'Afrique du Sud, le Royaume-Uni, et les États-Unis, mais maintenant il se trouve a la Nouvelle Zélande.
  • Suzanne Rosier is a climate scientist with a particular interest in extreme weather events. She uses climate models to try and understand the drivers behind extreme events, and how these might be changing with human influence. Sue previously worked in Oxford at ‘’, a highly successful climate model distributed computing project; she originally came to NIWA to help develop a version of this modelling for the Australia/New Zealand region, ‘weather@home ANZ’, which has been running successfully since 2014.

Inter-agency collaboration, a core principle in the development field, maximises impact of work of developing agencies and increases the value delivered to their stakeholders. For collaboration opportunities to be created, development organisations like SPC actively work on making their work transparent and visible to external actors.

As part of their effort towards increasing collaboration between agencies involved in the development sector in the Pacific, SPC and NIWA are organising a series of seminars in which some of their current and past work will be presented. The audience, in addition to staff members of these two organisations are stakeholders interested in SPC’s and NIWA’s work including MFAT, MBIE and others.

The topics covered in the webinars are topical and gravitate around use of advanced computing resources in solving problems in the fields of climate change, geoscience and fisheries among others. 

The topics and the dates are available in the related events below.

The events will be interpreted and recording of each of the sessions will be made available online.

Please contact the organiser, Dr Aleksandar Zivaljevic[email protected] for more information, for the invitation to the events or to express interest in webinars interpretation in French.
For matters related to communication, please contact Camille Menaouer, Digital Communications Coordinator at [email protected].
