Manage Your NZ Hazardous Substances Register in One Place.
Inventory by location, safety data sheets, threshold calculations and the controls your quantities require — the whole register, kept current.
The problem
A spreadsheet can't do the maths
Hazardous substances are one of the areas small organisations most often get wrong — not through negligence, but because the obligations depend on what you hold, how much, and where, and a spreadsheet can't work out which controls those quantities trigger.
SteadyOn keeps the inventory, the safety data sheets and the threshold logic together, so you can see not just what you have but what the law asks of you because of it.
What it manages
Inventory, SDS, thresholds, controls
Inventory
Record what you hold and how much — the substances on site and the quantities that determine your obligations.
By location
Quantities are tracked per place they're kept, because that's the grain the regulations actually apply to.
Safety data sheets
Keep every SDS attached and current, with expiry tracking so an out-of-date sheet doesn't slip through.
Threshold calculations
See which controls your quantities trigger — each with the threshold that fired it and the provision it comes from.
Controls report
A clear view of the controls your holdings require, so you can tell what's in place and what's outstanding.
Reviews & expiry
Review dates and SDS expiry reminders keep the register current instead of a snapshot from last year.
Built for the NZ hazardous substances regime
SteadyOn is built around New Zealand's hazardous substances framework under HSWA 2015 and the Hazardous Substances Regulations, with thresholds calculated in full. It helps you manage and evidence your duties — always confirm specifics with WorkSafe or the EPA; it is not legal advice.
- Inventory recorded by quantity and location
- Safety data sheets with expiry tracking
- Full NZ threshold calculations
- Controls report showing what each quantity triggers
- Review dates to keep the register current
- Links substances to sites, actions and documents
SteadyOn helps you manage and evidence your obligations — it does not replace legal advice. Always check the current requirements with your regulator.
Frequently asked questions
What has to be in a hazardous substances register in NZ?+
In practice you need to know what hazardous substances you hold, in what quantities and where, and have current safety data sheets available — the foundation for meeting your duties under HSWA 2015 and the Hazardous Substances Regulations. SteadyOn keeps all of that in one register; it helps you manage and evidence your obligations and is not a substitute for advice from WorkSafe or the EPA.
How are threshold quantities handled?+
SteadyOn calculates New Zealand thresholds in full: as you record quantities by location, it shows which controls those quantities trigger, the threshold that fired each one, and the provision behind it — so you can see the 'why', not just a yes/no.
Why track quantities by location rather than for the whole site?+
Because many hazardous-substance obligations apply at the place the substance is kept, not across the whole organisation. Tracking per location is what lets the threshold calculations be accurate.
Can I keep safety data sheets in the same place?+
Yes. Each substance carries its SDS as an attachment with expiry tracking, so the sheet and the inventory entry stay together and current.
