When Science Meets Soul

Every four years, the world's leading researchers, practitioners, and policymakers in weed biocontrol gather in one place. Last month, that place was Aotearoa, New Zealand, and HPCE Aotearoa was proud to bring it to life!

There are events you deliver, and then there are events you feel. The XVII International Symposium on Biological Control of Weeds, held at The Millennium Rotorua from 8–13 March 2026, was firmly the latter.

For six days, approximately 130 delegates from across the globe came together to share research, forge connections, and advance one of the world's most important environmental disciplines: the biological control of invasive plant species. As the premier international conference in its field, the stakes were high, and the bar was higher.

A Conference That Was So Much More

Walk into most scientific conferences, and you know exactly what you're getting: registration desks, lanyards, PowerPoints. The XVII Symposium was something different from the moment delegates arrived.

The programme wove together scientific sessions, poster presentations, workshops, field trips, a welcome function, an international wine evening, and a finale dinner, creating an experience that was as much about connection as it was about content. High-quality merchandise, an abundance of greenery, and a venue dressed with genuine care set the tone before a single session had begun.

Sophisticated. Exciting. Incredibly well-considered. Those were our first impressions walking in on Day 1. We heard similar words from delegates throughout the week.

Te Puia: The Moment That Set Everything Alight

If we had to choose one standout moment from the entire event, and it's a genuinely difficult choice, it would be the welcome function at Te Puia. The pōhiri, kapa haka and food were all wonderful elements.

For international delegates, it was an unforgettable introduction to Aotearoa. For locals, it was a moment of quiet pride. For everyone in that room, it was goosebump-inducing and the best possible start to an event of this scale and significance.

Cultural integration wasn't a box to tick on this event. Waiata, whakataukī, and a powerful opening by Kingi Biddle wove te ao Māori through the entire conference, giving it a sense of place and authenticity that elevated every moment. This is why it matters: when a host country shares its identity genuinely and generously, it transforms a conference into an experience people carry home with them.

Behind the Scenes: What Delegates Never Saw

Seamless events are rarely simple ones. The XVII Symposium had its share of complexity, though most of it was invisible to the people it could have affected most.

Global travel disruptions, driven by geopolitical tensions in the Middle East, meant some international delegates faced significant challenges with their planned routes. Flights needed to be urgently reconfigured and accommodation rebooked. Logistics restructured, both to Rotorua and home again.

Our approach was to stay calm and solutions-focused and keep communication flowing. No panic, just coordination; long phone calls, proactive problem-solving, and a genuine commitment to making sure that every delegate who wanted to be in that room could be.

Stova, our registration platform of choice, was instrumental in managing the complexity of delegate selections and ensuring the experience felt smooth and user-friendly from the very first click.

The Science That Brought the World to Rotorua

The programme itself was a reflection of how far the field of weed biocontrol has come and how much further it has to go.

Standout sessions explored Release, Establishment, and Post-Release Monitoring; Target Agent Selection; Bioherbicides; and Community Involvement and Education. Each topic carried both scientific depth and real-world urgency, reflecting a discipline grappling with genuinely significant environmental challenges.

What made the content resonate wasn't just its quality; it was its relevance. These are researchers and practitioners working on problems that matter. Bringing them together to share knowledge, challenge assumptions, and explore new directions is exactly what an event like this exists to do.

The Numbers and What They Mean

• ~130 delegates from across the international biocontrol community

• 84% of delegates reported being very satisfied with the event

• Event delivered on budget, despite the complexity of managing international travel disruptions

• Overwhelmingly positive feedback on organisation, AV quality, networking opportunities, and overall atmosphere

Attendance was slightly lower than originally hoped, a reflection of the global travel challenges rather than any lack of interest in the event. But with 130 highly engaged, deeply connected delegates, the quality of what happens in that room matters far more than the number of chairs filled.

What We're Most Proud Of

The complexity of bringing together a multi-faceted international event scientific programme, cultural experiences, social functions, field trips, international logistics, and making it feel effortless from the outside. Watching connections form between delegates who had previously only known each other through research papers. Hearing the feedback about how well-run everything was. Seeing people genuinely enjoy themselves at a scientific conference is rarer than it should be. There were so many highlights!

The relationships we built across this event with our clients, with delegates, with suppliers were the foundation on which everything else rested. That's not a cliché. It's the reality of how complex international events actually get delivered.

Why Events Like This Matter

Science advances fastest when the people doing it can be in the same room. When a researcher from New Zealand can share findings with a colleague from Europe, debate approaches with someone from South America, and walk away with ideas they couldn't have had sitting at their desk.

The XVII International Symposium on Biological Control of Weeds brought people together from across the globe to share knowledge, build connections, and collectively advance solutions to some of the world's most important environmental challenges.
