Irrigation New Zealand

In 2002-03, based on 425,000 ha of irrigation nationally, irrigation contributed $0.9 billion or 11% of farm gate GDP. In 2011/12, the study was repeated for the then 720,000 ha and estimated to contribute $2.2 billion. In 2015-16 it was estimated this figure had grown to $2.4 billion based on 800,000 ha irrigated. These figures are at farm gate and do not take account of the considerable flow-on benefits (processing and related service industries).

Looking at the future potential, the NZIER report of 2010, states increasing irrigable area by 350,000 ha increases national GDP by 0.8 %. A 2012 report by AERU, based on 500,000 ha of existing irrigation in Canterbury with a further 250,000 ha of new irrigation, reinforces this. It demonstrates the Canterbury economy receives an additional $2 billion in revenue, and just under 8,000 FTE’s, from the increased irrigation. For New Zealand wide impacts these numbers rise to $3 billion in revenue and just under 8,400 FTE’s.

There are considerable flow-on economic benefits to the community from irrigation. The Opuha Dam and the North Otago Irrigation Company ex-post studies show that farm expenditure, gross farm revenue and farm employment opportunities typically increase threefold when converting from dryland to irrigated agriculture. There are also large social benefits, including a higher household and personal incomes and a higher proportion of the population in full-time employment.

Wednesday 11 April–12 April

10:00 am - 17:00 pm

Join us for a two day Fertigation Master Class

When: 11th and 12th April 2018

Where: Lincoln Event Centre

Cost: $650 +GST

Places are limited so get in early to avoid disappointment.

The outcome of the class is to produce a resource that will provide irrigators with clear information for successful fertigation, including costs and benefits, good management practice knowledge resources and related training opportunities.

It will also enable irrigators and their service industries to inform and achieve any future regulations around fertigation equipment and practice.

The master class will help to unlock the future potential of fertigation in NZ through providing answers to the following questions –

  1. What are the costs and benefits of fertigation?
  2. What are the equipment options for fertigation and to which scenarios are they best applied?
  3. What does ‘good practice’ design, installation and management look like?

The programme involves presentations on each topic followed by discussion and agreement that these are industry accepted standards. There will be a field trip on the afternoon of day 1 as well as a dinner on the Wednesday night. Full programme will be released soon….

The price for the master class is $650 + GST

Notice of withdrawal: 7 days – 50% registration refunded or transferable to another person, 3 days – no refund – transferable to another person
