More freight moves through Tauranga than any other New Zealand port. Containers, logs, kiwifruit, dairy and bulk cargo, feeding a logistics, cold chain and horticulture economy that has grown around the port over the last two decades.
That concentration creates a specific risk profile. Heavy machinery and vehicle movement at scale, environmental obligations attached to coastal and harbour operations, and industrial control systems running cargo handling and cold chain infrastructure that were rarely designed with security in mind.
Why Bay of Plenty businesses certify
Safety certification is driven by port and logistics operations, transport contractors and horticulture packing facilities, where vehicle and machinery interaction produces the bulk of serious risk. Officer due diligence under the Health and Safety at Work Act 2015 applies the same way it does everywhere, and evidence is what discharges it.
Environmental obligations flow from Bay of Plenty Regional Council consents covering discharges, coastal activities and water take, alongside horticultural operations facing nutrient and spray management requirements.
Operational technology security is the emerging one. Container handling systems, bulk loading equipment, cold chain monitoring and packhouse automation all run industrial control systems, often maintained remotely by offshore vendors. IEC 62443 addresses that environment specifically, and almost no New Zealand consultancy is positioned on it.

Where we work
Port of Tauranga operations at Mount Maunganui and Sulphur Point. Logistics, cold storage and freight through Mount Maunganui, Te Maunga and Tauriko. Horticulture packing and processing across Te Puke, Katikati, Ōmokoroa and the wider Western Bay of Plenty.
Manufacturing and engineering in Judea, Greerton and Tauriko. We also work throughout Whakatāne, Rotorua, Ōpōtiki and the eastern Bay of Plenty, and into the central North Island forestry and processing belt.
Why ISO certification matters in Tauranga
Tauranga carries a national responsibility that its population size does not suggest. A significant share of New Zealand's exports and imports move across these wharves, and an extended disruption here reroutes supply chains for the whole country rather than for one region.
That concentration is why management systems matter more than they would at a smaller port. Safety exposure is high because vehicles, machinery and people share space continuously. Environmental obligations attach to harbour and coastal operations. And the automation running cargo handling, cold chain and packhouse lines is industrial control technology that corporate security frameworks do not reach.
For the horticulture businesses feeding the port, the driver is market access. Kiwifruit, avocado and produce exporters face buyer requirements for food safety certification, and packhouse and cold storage operators carry those requirements down the chain. Losing a certificate and losing a season's export channel can be the same event.
Industrial hubs and business precincts we serve
Bay of Plenty activity centres on the port and spreads through the horticultural districts.

How Nathan helps: implementation, certification and ongoing consulting
Tauranga engagements often span safety, environmental and operational technology exposure at once, so we scope across all three before recommending a sequence.
1. Implementation — building the system
We assess you against the standard and against HSWA and Bay of Plenty Regional Council obligations, then build the system around how cargo, produce and vehicles actually move through your operation. Where control systems are in scope the approach differs: passive asset discovery on live networks, zone and conduit design driven by consequence rather than existing network layout, and target security levels agreed with your engineering team rather than your IT team.
2. Certification support — getting you through assessment
For ISO 45001, 14001, 9001 and 22000 we shortlist JAS-ANZ accredited certification bodies and attend Stage 1 and Stage 2 with you. IEC 62443 follows a different route, with conformity assessment against specific parts depending on whether you are an asset owner, integrator or supplier, and we guide you to the right one.
3. Ongoing consulting — keeping the certificate live
Ports and packhouses upgrade equipment constantly, and each upgrade is a chance for the segmentation model to drift or a new vendor connection to appear unreviewed. We revisit the zone design and access arrangements on a cycle, alongside the recurring audit and surveillance work.
What you receive from us
Deliverables span safety, environmental and control system exposure, which is unusual for a region of this size.
Industries we work with
Port and terminal operations, log marshalling and export, container handling, freight and transport, and cold storage and coolstore operations.
We also work with kiwifruit, avocado and citrus packhouses, horticultural service businesses, marine and engineering contractors, wood processing operations, and manufacturers and distributors across the Western and Eastern Bay of Plenty.
How certification actually works, and where we fit
We run the gap analysis, design the system, produce the documentation, train your team, conduct your internal audit and facilitate your management review. When you are ready, we shortlist JAS-ANZ accredited certification bodies against your scope, sector and site and regional coverage, manage the quote process, and attend Stage 1 and Stage 2 with you. Findings raised at either stage are ours to close out.
Check the JAS-ANZ register before engaging anyone, and confirm the body is accredited for the scope you need. Unaccredited certificates are cheap, quick and routinely rejected by procurement teams, which means paying twice.
Frequently asked questions
No. We are an implementation consultancy. Certificates are issued by independent certification bodies accredited by JAS-ANZ. Accreditation rules prevent a body from certifying a system it helped build, so the consulting and certification roles must stay separate.
A JAS-ANZ accredited certification body of your choosing. We shortlist accredited bodies against your scope and sector, manage the quote process, and attend both audit stages with you. The certificate and the audit decision rest entirely with them.
Check the JAS-ANZ register and confirm the body is accredited for the specific standard and scope you need. Unaccredited certificates are widely available, inexpensive and routinely rejected by procurement teams, which means paying twice and starting over.
No consultancy honestly can, because the decision belongs to an independent auditor. What we can do is run your internal audit the way an external auditor would, close findings before assessment, and attend both stages so issues get resolved in the room.
It is the international series for industrial control system security. Cargo handling, bulk loading and cold chain systems are industrial automation environments, and corporate information security frameworks do not reach into them with enough technical depth.
Not currently. New Zealand has no critical infrastructure security statute. The Government consulted during 2026 on measures including potential legislation, and submissions have closed. Operators adopt IEC 62443 for risk and commercial reasons rather than regulatory ones.
Bay of Plenty Regional Council as the regional authority, with Tauranga City Council and Western Bay of Plenty District Council handling district plan and land use matters. Coastal and harbour activities carry additional consent requirements.
Yes. Packhouse and cold chain operations sit across safety, environmental and food safety obligations at once, and increasingly carry operational technology exposure through automation. We build those as one system rather than three.
Because industrial control systems were designed for reliability rather than security, and were then connected to networks. Cargo handling, refrigeration monitoring and packhouse lines all run on them, frequently with vendor remote access that nobody has assessed.
If your buyers require it, yes. Export produce channels commonly specify a scheme recognised by the Global Food Safety Initiative, and packhouse and coolstore operators inherit those requirements from the exporters they serve.
We plan attendance across shifts rather than during business hours, because a system that works at ten in the morning may not work at two in the morning. Auditors take the same approach for the same reason.
It shapes it. Certifying a packhouse during peak season is difficult, so we sequence the build so implementation and audit land outside your busiest weeks wherever the deadline allows.
Yes, through a single management system with sampled auditing. The scope statement names which sites are covered, and we word it so seasonal or leased sites are handled correctly.
