You can check the nitrate levels of your local river by visiting this interactive map from Statistics NZ https://statisticsnz.shinyapps.io/river_water_quality_nitrogen_apr17/
You’ll notice that the Forks Stream near Tekapo has a nitrate concentration of 3mg/L.
If you drive approximately 120 km west you’ll get to Hinds, where the Rhodes Stream has a nitrate concentration of 10.9mg/L. A little further north, the Boundary Drain reading is 10.3mg/L.
To put this into perspective the highest nitrate reading in NZ is 13.5mg/L in the market gardening capital of NZ, Pukekohe.

However, that is about to change. Despite many objections, Environment Canterbury has granted consent for a 15,000 cow dairy farm just outside of Tekapo.
