We believe it all starts with ‘people’.


Improve people’s professional and personal lives through innovation.


New Zealand businesses are world leaders who understand, embrace and value ethical behaviour and the contribution that people play in this success.


Encourage and support New Zealand businesses on their quest to be ethical ‘people-centred’ organisations.


Rata forms strong, long-term professional and personal relationships built on trust, honesty, integrity and ethics.

Rata Professional Services is widely recognized as having a unique holistic approach to business sustainability, its understanding and implementation. We believe it all starts with ‘people’.

Initially, Rata was solely focused on New Zealand organisations achieving sustainable business certification through the Rata Sustainable Certification Programme.

While certification is still important, Rata has developed other groundbreaking initiatives for New Zealand organisations to embrace.

Rata believes the initiatives it provides to New Zealand businesses are sound investment tools that add value to organisations and their culture.

Our Visual Identity

Whenever Rata communicates with its audience, we understand it is an opportunity to make the right professional impression.

The Rata visual identity plays an important role in our communications and is a snapshot of what our business is about. Our visual identity incorporates a New Zealand look, while also representing sustainability in the following ways:

  • The logo is a stylized image depicting the map of New Zealand.
  • The gap between the red and green imagery – not only represents Cook Strait, but also represents a never-ending path of continuous improvement which is essential for the future growth of businesses and their development incorporating ethics and sustainability.
  • The use of the red and green imagery depicts a Rata tree in full bloom.

Ultimately, we created a visual identity that we are extremely proud of.

The Rata name and logo are a registered trademark.

Sandra is a passionate Kiwi and Co-Founder of Rata Professional Services based in Wellington.

She enjoys playing her part to create a more productive New Zealand by creating smarter, healthier and more ethical practices to achieve work/life balance. She believes that the current system is failing to meet the needs of ‘New Zealanders’ – not to forget our children and future generations to come.

She also gains much enjoyment from surrounding herself with like-minded people and encouraging others to think ‘outside the box’ around self-development/self-reflection so that they can achieve their own professional and personal goals in life.

People who know Sandra well describe her as driven, thoughtful and determined, with a growth mindset and someone who is committed to creating a positive impact for businesses and communities.

Warren is considered, wise and articulate, with positive values and a strong, driven focus on ethical business practices. He strongly believes that this all starts with ‘people’.

As the co-founder of Rata Professional Services, Warren hopes to continue implementing practical business sustainability programmes that will become an integral part of many New Zealand organisations. He believes that these business programmes must inspire employees at all levels to be actively involved by encouraging ownership and accountability, which in turn creates an environment of positive, continuous change.

In the newest Rata initiative, the ‘Influence of 8’, the dream is to create positive change for employees, their families, wider communities and ultimately, within businesses which will add tremendous value to overall health, well-being and productivity in New Zealand.

Prior to co-founding Rata Professional Services, Warren was responsible for CatzDesign Ltd achieving Enviro-Mark Diamond certification within just 7 months, which was a New Zealand first.
