NIWA has developed an Environmental Forecasting Subscription Service (“NIWAFarmMet”). NIWA grants the User a non-exclusive, non-transferable licence to access to NIWAFarmMet in accordance with these terms. The access is granted for a period of one year from the date of purchase.

By accessing this service the User agrees to these Access Terms. The User may access NIWAFarmMet, any Information and/or associated Intellectual Property for their own internal purposes only.


NIWA will provide the User with password-controlled web-based access via the User's Computer. To support validation NIWA will limit the registration to the email address provided by the User. NIWA may collect that information about the User, and hold any such information at either NIWA’s registered, or Wellington regional offices. NIWA may use this information for statistical analysis, to provide services to the User, for marketing services or for research and development purposes. In managing that information, NIWA will comply with the provisions of the Privacy Act 1993.


NIWA will use reasonable endeavours to provide access to NIWAFarmMet 24-hours per day, subject to reasonable maintenance windows. NIWA will use reasonable endeavours to resolve any unavailability as soon as it can within working hours. NIWA’s goal is to ensure that NIWA FarmMet is available with 98.5% uptime during working hours on an annualised basis. From time to time it will be necessary for NIWA and/or its upstream providers to carry out work on NIWAFarmMet infrastructure in order to maintain and enhance its performance and security. NIWA therefore reserves the right to schedule periods of downtime to allow such work to be carried out. This downtime will normally be scheduled for periods of least impact to Users and they will be notified in advance.


NIWA will provide email and phone resources during working hours for the purpose of logging technical issues. NIWA will resolve the issues based on best endeavours.


Uncertainty is inherent in forecasts. While NIWA uses all reasonable endeavours to ensure the accuracy of the information provided by NIWAFarmMet, the information is provided “as is” without warranties of any kind, either express or implied, including accuracy, completeness, correctness, timeliness or fitness for any particular purpose. Accordingly, NIWA does not give any representation or warranty that:

    1. the information contains no errors, is complete or up-to-date; or
    2. the information may be used for any particular purpose, or give any particular results or outcomes; or
    3. the flow or provision of the information from NIWA will not be interrupted for whatever reason, or available at particular times; or
    4. the information or associated intellectual property will not infringe any third party’s intellectual property rights.

The User assumes the sole risk of assessing, evaluating, interpreting and applying the Information and that NIWA is not in any way liable for any loss, damage or injury suffered by the User, or any other person (whether in contract, tort (including negligence) or otherwise) due to the User’s use or possession of the Information or Licensed Intellectual Property or the existence of any errors therein.

NIWA accepts no liability for any interference with or damage to a User’s computer system, software or data occurring in connection with or relating to this service or its use. Users are encouraged to take appropriate and adequate precautions to ensure that whatever is selected from this site is free of viruses or other contamination that may interfere with or damage the User’s computer system, software or data.


If NIWA, upon reasonable grounds, believes that the User is breaching any term, including the terms and conditions of access, it reserves the right to immediately, and without notice to the User, restrict the User’s access.

NIWA may terminate access immediately, if the User breaches any of the terms of this Agreement and fails to remedy this breach within 5 days of receiving notice from NIWA to remedy the breach.


All proprietary rights (including all Intellectual Property rights) in, or associated with, the Information and Service are, and shall remain, vested solely in NIWA (or any other relevant third party who has contributed Intellectual Property for which NIWA acts as custodian). The licence contained within these Terms does not give the User (by implication or otherwise) any right to, or interest in, the Information, Forecasting Service or associated Intellectual Property other than the limited licence contained within this Agreement. Any rights not specifically granted in this Agreement are reserved by NIWA.
