The bore database

There are around 8,270 bores (wells) in Otago that access groundwater, usually using pumps.  ORC maintains an online database that displays important bore information: 

  • Bore location
  • Depth and diameter
  • Water level
  • Construction details
  • Geology (when available)

You can search for information on bores in Otago using a map or property address in the WellsNZ database or on Otago Maps 

What is groundwater?

Groundwater is fresh water found beneath  the surface of the earth. Groundwater is important for: 

  • Drinking and household needs 
  • Irrigation  
  • Supplying water to communities and businesses 
  • Industry 
  • Ecological processes like groundwater-fed streams and springs 

Why keeping our bore information up to date is important?

ORC aims to sustainably manage the quality and quantity of our groundwater. Knowing the location of bores and wells is essential for this work. However, the details of many bores in the database are missing or out of date, especially older bores that were drilled before the 1990s.  

Keeping bore information accurate and updated helps: 

  • Protect bore owners from possible water issues 
  • Ensure ORC can check if new groundwater use affects existing bores 
  • Manage and protect Otago’s groundwater supply. 

How you can help

In order to address these gaps in the database, ORC is working to update and verify bore information across the region to better manage and protect our precious groundwater. We’re offering free bore checks as part of this work and are keen to visit as many bores as possible in your area. A visit will be done by either ORC staff or a contractor.

During a visit, we would: 

  • Take GPS coordinates of your bore 
  • Take photos 
  • Check diameter, depth, and condition 
  • Measure water level (only if safe and accessible). 

A secure bore head is also important to protect your drinking water. If needed, we can advise on simple ways to improve your bore security

Want to help?

There are no penalties for bores that aren’t already in our database – we just want to improve the information we have so we can manage groundwater more effectively.

If you're happy for us to check your bore – or confirm if you have one – please contact us using the below online form or reaching out to us at science.groundwater@orc.govt.nz 

We’ll get back to you about arranging a visit.
