Te Ara Tatauranga - Statistics Consulting

Te Ara Tatauranga - The Statistics Consulting Group at the University of Waikato operates as part of the School of Computing & Mathematical Sciences. We provide expert statistical advice and support to postgraduate students and staff within the University and to external organisations.

Services provided

We provide general support on a variety of statistical and data related aspects. We also have mathematical modelling consultants. Our services include but are not limited to:

  • Experimental & survey design
  • Data cleaning & management
  • Statistical data analysis & data visualisations
  • Assistance with statistical software & programming
  • Advice on data ethics & Māori data sovereignty
  • Mathematical modelling
  • Numerical & computational methods


Our services and support are currently free for up to 4 hours per year for postgraduate students and staff at the University of Waikato. If additional hours are necessary, flexible arrangements will be made on a case by case basis. For projects external to the University, standard University of Waikato external consultancy fees will be charged. The consultant will provide a cost estimate and agreement before any work begins.

Appointments & enquiries

To make an initial appointment to see a member of the team, or for any other enquiries, please email and we will respond as soon as we can.
