How much does business insurance cost in NZ?
How much is a $1 million liability policy?
- General liability insurance for small businesses in NZ typically ranges from NZ$400 to NZ$800 per year per NZ$1 million coverage, according to industry estimates (InsureNZ – insurance guide).
- State offers tailored quotes based on your business type and risk profile, but does not publish standard pricing online.
- Wise NZ reports that most Kiwi small businesses pay between NZ$50 and NZ$200 per month for their business insurance (Wise NZ – small business insurance guide).
What factors affect business insurance premiums?
- Higher coverage limits increase premiums – public liability is a common example (Wise NZ).
- Claims history, business location (crime or natural-disaster risk), and the nature of your work all influence the final price (Wise NZ – risk factors).
- InsureNZ suggests that package policies for home‑based service businesses cost around NZ$500–NZ$1,500 per year, while larger operations may reach NZ$8,000 (InsureNZ – business insurance page).
A small retail shop in Wellington will pay a very different premium than a freelance graphic designer in Hamilton. Because State doesn’t publish prices, you must go through the quoting process to see where you land – and then compare that against at least two other insurers.
The implication: without a quote, you cannot estimate your own premium with State.
Is state insurance in NZ good?
What do customer reviews say about State?
- State has over 32,000 small business customers, which signals broad adoption.
- Online reviews are mixed. On Trustpilot, some customers praise the claims process while others report poor customer service – “hopeless customer service, over the phone” wrote one reviewer in 2023 (Trustpilot – State Insurance reviews).
- State won a Canstar 2025 Outstanding Value award for home & contents insurance, which suggests positive brand trust even though the award isn’t for business policies (Canstar – State award).
How does State compare to other insurers in NZ?
State, AMI, and NZI are all owned by the same parent – IAG New Zealand – so their business insurance products may share similar underwriting and pricing structures. IAG is the largest general insurance group in NZ (Wikipedia – IAG NZ). Independent providers like AA Insurance (a joint venture with Suncorp) offer alternative terms. The table below highlights the key similarities and differences.
| Feature | State | AMI | AA Insurance |
|---|---|---|---|
| Parent company | IAG NZ | IAG NZ | Suncorp / NZAA |
| Business liability cover | Yes | Yes | Yes |
| Online quote & purchase | Yes | Yes (AMI) | Yes (AA Insurance) |
| Contact | 0800 80 24 24 | 0800 100 200 | 0800 500 231 |
| Canstar award (2025) | Home & Contents | Home & Contents | Home & Contents |
The pattern: comparing State to AMI is an intra-group comparison, not a true market check.
Because State, AMI, and NZI are all IAG brands, shopping among them doesn’t give you true market competition. For a fair comparison, include at least one non-IAG insurer such as AA Insurance or Vero.
Do you need business insurance in NZ?
What happens if I don’t have business insurance?
- Without insurance, you’re personally liable for any lawsuits, property damage, or injury claims made against your business. Costs can quickly run into tens of thousands of dollars.
- Business.govt.nz advises that certain types of cover – such as employer liability – may be legally required, and failing to hold them can result in penalties (Business.govt.nz – insurance guidance).
What types of business insurance are mandatory in NZ?
- Employer liability insurance is required if you have staff (to cover injuries not covered by ACC) (MoneyHub NZ – business insurance guide).
- Motor vehicle insurance is mandatory for any business-owned vehicles that drive on public roads.
- Statutory liability insurance can help cover fines for unintentional breaches of New Zealand law (MoneyHub NZ).
Skipping insurance might save a few hundred dollars a year, but a single liability claim could wipe out a small business’s savings. Statutory liability cover is especially valuable if you work in a regulated industry.
The risk: the financial exposure of being uninsured far outweighs the premium cost for most businesses.
Are State and AMI the same company?
Who owns State insurance?
- State is a brand of IAG New Zealand, a wholly owned subsidiary of Insurance Australia Group Limited. IAG is the largest general insurer in New Zealand (Wikipedia – IAG NZ).
What other brands does IAG operate in NZ?
- IAG New Zealand’s stable includes State, AMI, NZI, Lumley, and Swann Insurance (Wikipedia – IAG brands).
- That means a large share of the NZ business insurance market is controlled by one corporate group.
The catch: shopping only within IAG brands gives no competitive tension.
Why is insurance so expensive in NZ?
What is driving insurance premium increases across New Zealand?
- Higher reinsurance costs (global insurers charging more to cover NZ’s risk profile) are a key factor.
- Natural disasters have become more frequent and severe – the 2023 Auckland floods and Cyclone Gabrielle alone caused billions in insured losses.
- Claims inflation – the rising cost of materials and labour to repair buildings and vehicles – pushes premiums up across the board.
How can small businesses reduce their insurance costs?
- Bundle multiple policies (e.g., liability + property + vehicle) with the same insurer for a discount.
- Increase your excess (deductible) to lower the annual premium.
- Improve risk management: install security systems, maintain equipment, and train staff on safety.
- State’s own blog suggests starting with a business plan and risk identification before choosing cover – a targeted policy is often cheaper than a generic one (State Insurance NZ – steps to insuring your business).
A higher excess lowers your premium but means you pay more out of pocket if you make a claim. For a small business with thin cash flow, a moderate excess is often the sweet spot.

Final takeaway
State Insurance offers a straightforward path to business insurance, especially for NZ small businesses that want an online quote and the backing of a large group. The main risk is market concentration — with State, AMI, and NZI all under IAG, you may not get the most competitive price unless you also check insurers outside the IAG family. For a business owner, the choice is clear: get a State quote, then compare it with at least two non-IAG providers before signing.
