Regulatory Update

Below is a quick update on where things have gotten too from a regulatory perspective. 


2017 saw Environment Canterbury (ECan) introduce Good Management Practices (GMP) into its Land and Water Plan framework.  This is known as Plan Change 5.  Plan Change 5 also introduced the Waitaki specific nutrient management rules.  The decisions on the plan were appealed by a number of parties, particularly in relation to how the irrigation and fertiliser GMP’s were being treated in the Farm Portal (the online tool developed to determine exactly what GMP is at a farm level).  Appeals are still yet to be resolved, and therefore, it is likely to be mid-2018 before this plan is made operative.

Plan Change 2, which is specific to the Hinds Plains region, is also still under appeal, however, Plan Change 3, which is specific to the South Canterbury Coastal Streams area, had all its appeals resolved in November 2017, and is now fully operative.

ECan has also been doing a big push in the areas where a consent to farm is required, to encourage those who need one to go through the process.  There has been a good response to this (contrary to the opinion of Dr. Mike Joy) as the process is new to many, and requires professional help and a change in mindset for many. 


Otago’s nutrient management rules are now two years away from kicking in (the date is 1 April 2020).  Otago Regional Council has been encouraging farmers to get their Overseer done.  They have also taken the initiative in the more sensitive catchments such as the Kakanui, and have been providing resources and funding to assist with this.

Southland’s Land and Water Plan is nearing the completion of hearings.  Council gave its reply report and recommendations (a summary of all the information and submissions presented to the hearings panel, and answers to all questions from the panel during the hearing) in November 2017.  Watch this space.


Horizons One Plan struck a major hurdle in early 2017, with the Environment Court deciding that the way in which the Council was implementing its plan was not what the plan actually said.  This has left the council with a plan that effectively doesn’t practically work as it was written, and wondering what to do now.  Implementing the plan as written creates a massive cost to farmers and other consent holders, and doesn’t necessarily achieve the desired water quality outcomes.  Given this, in August 2017, the council voted to investigate the possibility of a partial plan change.  However, this will not be a quick or easy process as it is both a legal and public process.

Hawkes Bay

Irrigators in the Tukituki catchment are left high and dry (literally) after the Ruataniwha Dam project is put on the shelf indefinitely.  The Tukutuki River minimum flow is still going up, and without the dam to augment and flush the river, the increase in minimum flow will mean the possibility of severe restrictions for irrigators in this catchment.  Effectively, the raise in minimum flow was coupled with the dam, but the impacts of de-coupling are now about to be realised.


Gisborne’s Freshwater Plan decision was released in August 2017, and was subsequently appealed.  The appeals are still to be worked through and there is no timeframe at this stage on when appeals are likely to be resolved.  Gisborne’s Freshwater Plan was actually pretty kind from a nutrient management perspective when compared to Canterbury for example.  There is no requirement for on farm limits using Overseer, and they have adopted a Farm Environment Plan approach to managing water quality.  However, it does have some issues with water quantity.  As horticulture, and kiwifruit in particular, look set to increase, those looking in the Gisborne area for plots to develop are soon realising that there is basically no water available for allocation unless you are prepared to take high flow water and store it.  Therefore, this is limiting the potential for the Gisborne region.


As well as all that is going on the regions, we have a new government who looks set to wind up funding irrigation scheme development, has already taken a stand on climate change, and will undoubtedly want to stamp its feet on the water issues.  2018 will be an interesting year…

The Importance of Timeframes – Resource Consent Timeframes That Is…

Christmas seems to be a magic deadline for people – apparently the 25th of December is the date at which the professional world as we know it will cease to exist and heaven help us if we miss it.

While Christmas is more of a perceived deadline for things, there are some real resource consent timeframes or deadlines that you should be aware of.   As over-allocation of our resources has become an issue, so has the methods by which councils can use to reduce over-allocation.  This is where timeframes around consenting are beginning to bite and councils are actually using their powers. 

Lapse Date and the Cancellation of a Consent

The first is the lapse date on a resource consent.  This is not the expiry date, but rather the “use it or lose it” date.  From the date of grant of a consent, you have up to five years to use the consent, or you lose it.  This is particularly important in over allocated water catchments for example as lapsing a consent is one of the mechanisms that a council will use to claw back over allocation.  You may apply to the council to extend your lapse date, but you have to be able to demonstrate to the council that you have taken considerable action towards actually using the consent.  The maximum extension that would normally be given is a further two years.

Even if a consent has been used before the lapse date, it can still re-lapse if it is not used for a five-year period after that, so this is something that you also need to be aware of.   This is referred to as cancellation of a consent. 

Renewal of Existing Consents

There are also important deadlines around renewing resource consents.  An application to renew a consent that is received by the council at least six months prior to the expiry of the consent is guaranteed to be given ‘continuation’.  What this means is that you can continue to operate under your existing consent until such time that a decision is made on the replacement.  Getting continuation is critical if processing the renewal is likely to take considerable time like we have seen here in Canterbury where renewal applications have spent years in process waiting on plans to be developed. 

A renewal application received after six months but before three months of the expiry date may get given continuation, but it is at the council’s discretion. 

Securing continuation also means that you have priority to a resource over someone else competing for the same resource.  So again, if we think water permits where a resource is nearing its full allocation, you want to be able to re-secure your access to that water ahead of a new user.   

If you find yourself within the three-month window, then continuation cannot be given, and you must cease your activity at the expiry date.  If you are in an over-allocation situation again, this may cause issues with your renewal, and there is a risk of the council not granting the renewal consent (another way to claw back over-allocation). 

Expiry Date

Once a consent expires, and if no application has been received by the council to renew the consent within the required timeframes, then you no longer hold a consent to undertake that activity or have any right at all to renew it.  If you find yourself in this situation, and you do want to carry on undertaking your consented activity, then you have to apply as if you are a brand-new consent.  In over-allocated areas, you may not even be able to apply for consent as many councils have now made it a prohibited activity to apply for consent in over-allocated areas.  Prohibited means that you cannot even apply to the council – the door is shut tight. 

These dates are all things that any consent holder needs to know.  A resource consent is not an unlimited right for unfettered access to a resource, or to undertake an activity.  It can be revoked by not using it, or by failing to meet the timeframes around the renewal process.  

Also, a small request from this consultant.  An application for resource consent can take a fair amount of time to prepare – even if it is for a renewal, the amount of information required to be supplied is just the same as it is for a new application.  Therefore, please give your consultant plenty of time to get the application in – it is no good fronting up a week before the application must be submitted and expecting that it can and will be done in that timeframe, and the same goes for that magic Christmas deadline…

Useful Farming Technology Apps and Websites

Technology – there are those who embrace it with open arms, and then there are those who don’t… but love it or hate it, there are some very good pieces of technology that could be extremely useful for farmers wanting help with environmental compliance, or even just some advice and support.  And, with the increased need to be accountable and “doing things right”, these are some of the technology tools and resources that I have come across in my day job that I thought were worth a mention. 

Riparian Planner

This is an online tool developed by DairyNZ.  It is a step by step process to design, budget and prioritise water management on farm.  It is extremely user friendly, and a good starting point if you are considering riparian planting on your farm.  This is a useful tool for all types of farms.  The web page address is as follows:

Check-It Bucket Test app

This is available for both Apple and Android devices via the App Store or Google Play Store.  The app walks you through an annual performance assessment of your irrigation system, provides the results instantly to your device and e-mails a final report to you.  This is a great way to check whether your irrigation system is performing as you expect.  Is water being applied evenly?  Are you putting on what your control box says you are putting on?  You do need to own a few buckets to carry out the test, but the insight into your irrigation systems performance is well worth the trip to town to invest in the buckets.  Some irrigation schemes do have buckets that you can borrow for this purpose, so ask around too. 

Soil Moisture Monitoring

Soil moisture monitoring equipment is by no means new technology, but the amount of it now on the market has increased substantially and understanding what is the right tool for you can be difficult to work out. You must choose the right equipment for your soil, land use activities and irrigation system type, and then locate, install and calibrate (if necessary) it correctly. Accessing, managing and understanding the data is also important. If soil moisture monitoring is to be successful, each of these aspects has to be carefully worked through.  Irrigation New Zealand has developed a resource book for this very topic and it can be found here:

Online GIS systems

For those of us here in Canterbury, Canterbury Maps is an amazing resource.  Not only can you create farm maps, but it can be used to search for information about any property, consent information, bore information, and any other relevant information that you may need such as nutrient allocation zones, the location of wetlands or Runanga sensitive areas.  This can be found here:

Other councils do have online GIS systems, but none are quite to the level of Canterbury Maps.  But check out what your local council does have.  Understanding what is of interest and/or significance on and around your farm is key these days. 
FDE Calculator app

Dairy NZ has developed an app to allow you to work out how to manage your Farm Dairy Effluent (FDE).  You can easily calculate nutrient loadings and application rates, therefore enabling application of effluent with greater precision.  It can be used for diluted dairy effluent as well as for slurry tankers and muck spreaders.  This is also available for both Apple and Android devices via the App Store or Google Play Store.

I hope you find this information useful, and please let me know of any others that you think might be worth checking out.

Technology Transforming New Zealand Irrigation

The latest issue of the IrrigationNZ News (Spring 2017) features an excellent and in-depth article on how technology is transforming irrigation in New Zealand. Featuring six case studies from throughout the country describing the different technologies applied on each farm - from soil moisture sensors to weather forecasting options to automated irrigation systems "designed to deliver the right amount of water at the right time".

Many of the technologies discussed have been previously showcased on our H2Grow blog so if you are interested to find out more follow this link and turn to page 28 => IrrigationNZ News: Spring 2017

Overlooking the North Otago dairy farm run by Nick Webster part of the "Peter Mitchell and Nick Webster" case study discussing how they use Growsmart Precision VRI technology to improve their operation.

Asian Australasian PA Conference: New challenges and New Tech

Hamilton hosted the International Tri-Conference in Precision Agriculture last week and the event was a huge success. Approximately 500 delegates from around the world descended on Hamilton for a very full on three days of discussion around networking in the Precision Ag field. The tri-conference had speakers in both precision livestock and arable fields.
Livestock data collection is a major part of management on the LIC farm. 
I had three key takeaways from some of the speakers. A lot of discussion was had around the implementation of the new technologies on farm. As the technologies mature it is becoming apparent that adoption of the technology is going to be a big hurdle that the industry will need to tackle.

Data and sensors. How do we tell right from wrong?
Jeff Bewley spoke on the implementation of sensors into the management of dairy cows. Just imagine cows covered in sensors. Monitoring cows is one thing, using the data is the other. Jeff described the benefits of monitoring cows which is readily apparent, heat detection, illness detection and behaviour analysis all allow for management of each animal. However as Jeff points out 3 different sensors that all claim to measure the same thing give three different results. The question of repeatability and accuracy is then called into question? Who is right and who is wrong?

Ethics will come into play
With the ability to monitor each individual animal comes an increased level of responsibility. Derek Bailey has been monitoring cattle in the rangelands of the USA and has found that knowing if an animal is unwell poses a bit of a conundrum. Knowing that an animal is sick is useful. Knowing where it is exactly is also useful. Answering the question of how to treat it when it is out on the ranges and whether the cost of treatment outweighs the benefits is a tougher decision. Easier to balance the maths with cattle, but in the case of old wethers the decision becomes decidedly more ethical than commercial.

Satellites to help measure many things.
Wide scale soil moisture measurement has the potential to facilitate highly accurate irrigation scheduling. Istvan Hadju from Massey University presented his findings into the use of satellite based radar to sense the soil moisture in the top of the soil profile. Istvan still has some work to do but utilising the AquaCheck probes he has been able to accurately map soil moisture in approximately the top 7cm of the profile. This work has some exciting implications, including being unaffected by clouds. Perfect for the land of the long white cloud!
