Water New Zealand and IWA-ASPIRE Conference 2025
29 September – 03 October
Together We Shape the Future of Water
We’re proud to sponsor and participate in the 10th IWA-ASPIRE Conference and Water New Zealand Conference and Expo 2025, the leading event for water, sanitation, and environmental professionals in Aotearoa New Zealand and the Asia-Pacific region.
This year, the International Water Association (IWA) and Water New Zealand are joining forces to deliver an innovative, future-focused conference. As attendees and contributors, we’re excited to join global and local experts in Christchurch to address the most pressing water challenges, share indigenous knowledge, and explore smart water solutions for resilient communities.
Award Nominee
We are honoured to be a finalist for the Water New Zealand Excellence Awards – specifically, the Morphum Environmental Sustainability Award for the Maitai Aeration System, on behalf of our client, Nelson City Council. This recognition highlights our commitment to sustainable water management and environmental innovation. This project, led by Ollie Whalley from the Nelson office, included a team of consultants to deliver an innovative engineering solution that raised the level of dissolved oxygen in the Maitai River, a treasured taonga for the people of Nelson, past, present, and future.
Event Speakers
- Wioletta Gilfoyle, David Wyllie, and Jackie Colliar (Hamilton City Council) – Unlocking the value of hydraulic models for intensification planning in water supply and wastewater models
- Katherine Cowper-Heays – South Dunedin Future: Outlining the case for change

Futurespace 2025
08–09 October
Futurespace is the premier leadership and consulting conference for New Zealand’s engineering and environmental sectors. This year’s theme, “Leadership of the Future,” explores how we can lead through complexity, foster innovation, and deliver sustainable infrastructure for our communities.
Join industry leaders, including Tonkin + Taylor’s own Simonne Eldridge, Technical Director – Environmental Engineering, who will present “Beyond the contract – why collaboration, not the model, delivers infrastructure success.” With decades of global experience, Simonne will share how collaborative leadership drives resilience and innovation in infrastructure delivery.
This two-day event is designed for executives, emerging leaders, consultants, and innovators looking to grow their leadership capability and navigate the challenges of economic uncertainty, AI disruption, and global change.

New Zealand Geotechnical Society Symposium
15-18 October 2025
This October, Tonkin + Taylor is proud to be part of the New Zealand Geotechnical Society Symposium as gold sponsors. This event is a gathering of the brightest minds in geotechnical engineering. With over 60 years of technical excellence behind us, we’re excited to engage with industry leaders, share insights, and explore the innovations shaping the future of our field. As an employee-owned group of environmental and engineering consultancies, we’re passionate about collaboration, risk-informed design, and delivering resilient solutions across Aotearoa, Australia, and beyond.
