The Shamrock Group is a New Zealand owned and operated chemical manufacturer, supplying and manufacturing specialty chemicals for a range of NZ industries. With our own manufacturing facility and an in-house chemist, we can formulate new chemicals or reformulate existing products to suit your requirements, then manufacture them at scale.
We’re also the last of the chemical companies in New Zealand providing specialty chemicals for the leather and textile sectors left in the country – a sector we remain committed to as it consolidates.
As a New Zealand-owned chemical manufacturing company, we offer the kind of close collaboration and fast turnaround that isn’t possible when working with an offshore supplier.
Custom Chemical Services Across a Range of Industries
While leather and textiles remain core to our business, our chemical manufacturing capabilities extend well beyond these sectors.
We supply:
Leather and textile processing chemicals
Surfactants, degreasing agents, detergents and specialty auxiliaries
Agricultural adjuvant chemicals
Custom blends for agricultural applications
Building and construction products
Including bonding and specialty formulations for the building industry
Waste management applications
Including dust suppression and odour control products
General industrial and process chemicals
Custom blends for oil, industrial and process applications
If you’re unsure whether your project is a good fit, get in touch and we’ll let you know.
Toll and Contract Chemical Manufacturing
We offer two manufacturing arrangements, depending on what suits your business:
| Toll Manufacturing | Contract Manufacturing |
|---|---|
| You supply the raw materials and recipe, and we manufacture to your specification for a processing fee. | You provide the recipe or specification, and we source some or all of the raw materials on your behalf, in addition to manufacturing. |
Both are available across liquid and powder blending, and across a range of chemical hazard classes.
Manufacturing Formats and Capacity
We manufacture chemicals in bulk formats to suit commercial and industrial customers, including:
- 20–25 litre jerrycans
- Drums
- Intermediate Bulk Containers (IBCs)
- 20–25kg powder bags
This bulk focus means we’re set up for ongoing commercial supply rather than small consumer packaging.
From Formulation to Manufacturing: Flexible to Your Needs
Because we have both a manufacturing facility and an in-house chemist, we’re not limited to producing chemicals to a fixed recipe. Our process is straightforward:
Project definition
We start by understanding your requirements – the application, performance targets, and any constraints around materials or manufacturing.
Formulation or reformulation
If required, our in-house chemist develops a new formulation or refines an existing one, sourcing materials through our supplier network in NZ and Asia.
Sampling & approval
We produce samples for your evaluation. We iterate until the formulation meets your requirements.
Scale-up & manufacture
Once approved, we move into production using our in-house liquid and powder blending equipment.
Formulation and manufacturing under one roof means no handover delays or supplier changes.
Why Choose an NZ-Based Chemical Manufacturer?
NZ owned and operated
There are fewer chemical companies in New Zealand than ever before. By working with local chemical manufacturers in Auckland, your project stays local, and so does accountability.
Direct communication
Work with our team and chemist directly, not through an offshore intermediary.
Faster turnaround
Fewer delays when everyone is in the same time zone.
Proven manufacturing capability
From leather and textile chemicals to agricultural, building and waste management products.
Quality assured
Our processes are ISO 9001 certified.
