A new name.
A reinforced commitment.

Formerly known as NDA New Zealand and Australia, we have recently rebranded to Tīra to more accurately represent who we are and what we believe in.

Tīra is Māori for steel – the core material at the heart of our business. It is an acknowledgement of our strengths, our heritage and our commitment to the future.

The name Tīra stems from both English and Māori, paying tribute to our long and strong Kiwi history (since 1894), the diversity of our employees and customers, and our reinforced commitment to our people, our partners and partnerships, our environment and the future.

While we have a fresh new brand and a refreshed approach with a renewed focus, you can be assured that we’re the same leading team of engineering experts that you’ve come to know and rely on – and who will strive to ensure we deliver excellence, every time.

Our story: from strength to strength

From grassroots beginnings in Taranaki, Tīra has come a long way, gaining new capabilities and acquiring new companies over the years so that we can service industries around the globe.

NDA – Proud History | Confident Future

2021 NDA rebrands to Tīra.

Tira Crown

1894 a strong start

Tīra’s story starts as far back as 1894, when National Dairy Association (NDA) was established in Hawera, Taranaki, as a co-operative for New Zealand’s primary sector. It was a production hub for the farming industry, supplying everything from gumboots to milk cans.

1950’s a growth industry

By the 1950s, NDA had channelled its focus to manufacturing stainless steel vessels and vats for the burgeoning New Zealand dairy industry. The merging of co-operatives into single, larger entities created a need for vessels of greater capacities – and NDA seized this opportunity.


2000’s A new century. A new structure

By the early 21st century, turnover had almost doubled, and the globalisation strategy was gaining momentum. To enable further growth, the Group started work on a capital restructure. Sydney-based Pemba Capital Partners acquired 60% of the Group in 2007, with the management team retaining 40% ownership.

2008 to

2010 a time of acquisition

We acquired Crown Sheetmetal in 2008, a wine and dairy tank specialist fabricator with workshops in Invercargill and Melbourne. With that acquisition, NDA gained full ownership of Truform Stainless in Blenheim – another fabricator serving the wine industry.

Around the same time, we also acquired Pipetech, an Adelaide-based specialist in the design and manufacture of pressure vessels for the mining, oil and gas industries.

2014 to

2018 strengthening our expansion

To broaden our offering across the wine industry to include drains, catwalks and services, we purchased Stainless Systems in 2014, growing it into a solution-based business with an excellent repeat client base.

2017 saw a drive for technology and automation with the acquisition of Taylors Engineering plant with its innovative fabrication technology and deep understanding of innovation.

During this time, the business start to diversify further and our ‘3 Waters’ focus began to evolve.

2019 a focus on innovation

Our specialist innovation division, innovex, was established in 2019 to ensure innovation and product development sit at the heart of our business – enabling us to commercialise our technology and create ground-breaking solutions to our clients’ problems.

2021 new brand, strengthened commitment

With the expansion into new industries and new ways of working, NDA rebranded to Tīra in 2021 to better represent our modern, innovative approach and the dynamic and diverse markets in which we operate.

We’re already Australasia’s largest speciality alloy fabricator, and we know that our resources will continue to grow in the future. For more than 125 years, our team of expert engineers have provided superior products and services to our customers – and that remains at the core of who we are today.

How we work

At the centre of our business are the key values of caring, integrity, courageous, and excellence. We work to bring these values to life, every day.

New Zealand is a special place and home to a vibrant, multicultural society, so we aim to reflect that diversity by creating a caring and inclusive environment – one in which we prioritise and care for our people and our place. At Tīra, we champion sustainability, safety and wellbeing, and strive to create an organisation where people want to work and to make a difference for themselves, their whānau, the business, our customers, the environment and our communities.

Another of our core values is courageous – having the courage to challenge the now and lead the future. We support and encourage innovative thinking, and advocate for and contribute to opportunities to shape our future. And we have a real focus on ensuring everything we do leaves our world in a better place for future generations.

Striving for excellence is also a core part of Tīra’s DNA. We ask how we solve our customers’ problems, and to make things work better. We champion a continuous improvement culture that focuses on excellence every day, in every way.

Lastly, and just as importantly, integrity is also at the heart of our business: we do what’s right and we do what we say we will.

Clint Brown

His previous positions in the sector included Regional Manager Australia and NZ, Managing Director NZ, and Operations Manager and Project Director/Manager. Clint also attended business programmes in Melbourne, Australia and Lausanne, Switzerland.

Life and experience in both New Zealand and abroad has given Melinda the opportunity to complete various studies from a BBS (HRM), NEBOSH Cert through to auditing. Giving people a chance to develop is her motivation, and she says her ability to name a family member in almost every town in New Zealand comes from her large whānau.

He was appointed as a Site Forman on the large Kiwi Dairy expansion in Hawera, and then saw plenty of sites around New Zealand as Site Forman for the next eight years.

Craig then joined Challenge Engineering in project engineering and project manager roles, but Tīra must be ‘in his blood’ because the company re-joined Tīra in 2000. Since then, Craig has held several project and general management positions, and is currently General Manager, Sales and Development.
