The challenge

Protecting the whenua and our natural resources often involves gradual changes to how we manage activities on land. With this in mind the Government set freshwater regulations for the maximum amount of synthetic nitrogen fertiliser that can be applied to grazed land, with a requirement for dairy farmers to report on their levels of its application.

Synthetic nitrogen fertiliser can leach through soil and into our waterways, with detrimental impacts on the surrounding ecology and our drinking water supplies. Understanding its application provides regional and central government the visibility on these land management practices, enabling them to act to continue to protect our freshwater over time.

Te Uru Kahika (the regional sector) came together, with support from Regional Software Holdings Limited (RSHL), the fertiliser industry and Media Suite, to develop a single portal for reporting on synthetic nitrogen fertiliser application.

The solution

The fertiliser industry already has tools to report on farm fertiliser application. However, Te Uru Kahika also needed to enable direct reporting from those farmers not registered with these tools. A solution was also needed quickly to meet the government reporting deadlines.

Media Suite’s tech platform enabled the rapid delivery of a system that made it easy for farmers to provide data on the fertiliser application across their property. This data is sent to a central repository hosted by Environment Canterbury and combined with the data provided from the fertiliser industry tools via API. This enables anonymised reports to be compiled for each regional council and national reporting for the Ministry for the Environment.

This solution means farmers only need to provide their data once, via a system that best suits them. These efficiency gains also extend to the regional sector, where a standardised national data structure means less manual reporting effort by council staff.

It felt seamless to work with Media Suite given the work they have previously done with the regional sector. They were really responsive to our requests yet also prepared to offer alternative solutions that were practical and most importantly could be implemented with our very tight timeframes.

The tool was stood up very quickly – we really appreciated Media Suite’s ability to navigate us through getting something up and running in a way that allows it to be refined over time.

  1. Reducing the burden on farmers to provide the necessary data
  2. Integration with existing industry tools to reduce duplicate effort
  3. Improving reporting efficiency both regionally and nationally

how it came together


Working with IT specialists from across Te Uru Kahika and industry to deliver a unified solution.

Technically speaking

“Our design system and msAF tech platform enabled us to really hit the ground running on this project, which was crucial given the tight timeframes.

For example, our Keycloak authentication module enabled us to rapidly configure the user registration and self-management aspects of the solution. The front-end React components, modelled on our design system, provided the developers the flexibility to quickly build out the forms to match Environment Canterbury’s API structure.
