Council Time Series Data

Time series data from the regional council is available as open data, and processing codes, metadata and descriptions are found here.

Hawke’s Bay Regional Council Time Series Data is available below. Details of the methods of obtaining data from this service are contained in the document Hilltop Server (Web Service).

Time Series Data

Data is provided under the open data Creative Commons By 4.0 attribution licence, and is subject to the Regional Council standard disclaimers.

These data services are continually being refined and improved.  More information and data is being made available through them each day.

All data should be treated as raw and care needs to be taken when using the data as it may have been obtained for specific purposes and be unsuitable for, or of limited use for other purposes.  the Regional Council are working to provide additional metadata to improve data interpretation. This is an ongoing project and will take time to complete.

All data that is available via web services is provided as XML data.  XML can be read and displayed by spreadsheet programs, or scripts can be written to automate and aggregate the process.  Some code may be available on services such as GitHub, for time series data search for ‘Hilltop’ and then select the scripting language you are interested in.

Some example requests are described in the Working Examples” document.

the Regional Council requests that anyone developing a useful application from this data to share a link with us.  We’d like to see how this data is used.   



Additional Site metadata for some sites is available from the LAWA Monitoring Sites Reference Data web service on the GIS Open Data portal.

The raw xml is available here.


Additional metadata is available for the Water Quality samples by performing a second request, but with the Measurement set to WQ Sample.  An overview of the the Regional Council Water Quality metadata is provided here.

Quality Codes

Some of the time series information has been quality coded to flag its fitness for purpose.  This information is provided as a number code in the Quality Code tag available via Hilltop requests. For simple time series information a separate request is required to obtain the quality code information, for Water Quality data the quality code is associated with the data. Where available, NEMS standards have been used for quality coding. However these do not exist for all measurements, and they have only been in existence for a few years.  Other quality codes associated with the data are:


Hydrology Processing Codes

Quality Code Description
0 or blank Raw
1 Synthetic
2 Processed
3 Checked & Compliant
4 Non-Compliant


Continuous Water Quality Processing codes

Continuous Water Quality has been coded to NEMS standard.  An overview of the schema is provided here.

 Quality Code Description 
 0 or blank  Non Verified or raw
 100  Missing record or impossible value
 200  Unknown quality
 300  Synthetic
 400  Compromised
 500  Fair
 600  Good


Discrete Water Quality Processing Codes

Discrete Water quality data has been quality coded according to a draft NEMS standard issued in 2014.  An overview of the schema is provided here.  The codes mimic the NEMS standards codes.

 Quality Code Description 
 0 or blank  Non Verified or raw
 10  Missing record or impossible value
 20  Unknown quality
 30  Synthetic
 40  Compromised
 50  Fair
