The NZ Arb Annual Conference 2026, themed 'Roots of Resilience', runs 29–31 October 2026 at the Energy Events Centre in Rotorua, organised by the New Zealand Arboricultural Association with OnCue Conferences. It features international keynotes from the UK and USA, a business and technical programme, and the concurrent Husqvarna National Tree Climbing Championship.
The New Zealand Arboricultural Association will hold its 2026 Annual Conference from 29 to 31 October 2026 at the Energy Events Centre in Rotorua, according to the event's dedicated website at nzarbconference.co.nz. Themed "Roots of Resilience," the programme spans tree management, climate adaptation, safety and industry development, and runs alongside the Husqvarna National Tree Climbing Championship.
The conference site is live, with the programme, registration and accommodation pages all confirming the Rotorua dates and venue.
The conference is organised by the New Zealand Arboricultural Association (NZ Arb), in association with Asplundh, with conference management handled by OnCue Conferences, per the event website. NZ Arb describes itself on nzarb.org.nz as the leading voice of arboriculture in Aotearoa and has represented the tree-care profession since its establishment in 1989, giving the annual conference a long-running institutional base.
The event is aimed at arboriculture professionals, from climbers and contractors to urban-forest managers. The 2026 programme, published on the conference site, features two international keynotes: Dr Andrew Hirons of Myerscough College in the UK, speaking on tree selection for a changing climate and applied tree biology, and Em Roberts of Clackamas College in the USA, on ethics and collaboration in arboriculture. Core sessions cover storm resilience, utility arboriculture safety, forest pathology, tree risk assessment and industry regulation, alongside a business stream on team management and scaling operations. The concurrent Husqvarna National Tree Climbing Championship, the Hansa New Arborist of the Year and an Industry Awards Dinner round out the week, with optional field trips.
The Energy Events Centre sits in Government Gardens on the edge of Lake Rotorua. Per Rotorua NZ's venue listing, it seats up to 4,000 delegates theatre-style (2,600 for a banquet) and includes the pillar-free 3,500-square-metre Unison Arena, with extensive free parking and walking-distance access to the CBD, restaurants and spa facilities. The conference's accommodation page lists the Millennium, Sudima, Pullman, Novotel and Ibis hotels, all in central or lakeside Rotorua close to the venue, making the event highly walkable for delegates.
The conference is a recurring national association event that fills a mid-week slot in late October at one of the North Island's largest purpose-built conference venues, pairing an indoor programme with outdoor competition space. Its established organiser, professional conference management and confirmed international speaker line-up make it a reliable fixture for Rotorua's business-events calendar and a useful example of a sector association anchoring multi-day delegate activity outside the main centres.
