Family owned and operated

Central Injection Agri is more than just an agricultural contracting company; we are a family owned and operated ag contractor deeply connected to the agricultural landscape of South Canterbury.

Central Injection Agri was established by Irishman Tom O’Keeffe and has since evolved into a family-run business that now includes our sons, Flynn and Alex, who are integral to our operations. We take pride in being a mobile service provider, completing a variety of extensive projects throughout Mid and South Canterbury, and expanding our reach into the Mackenzie Country.

What we do

Efficient, cost-effective, environmentally friendly

CIA Ltd specialises in efficient, cost-effective and environmentally friendly slurry management. Our services include liquid slurry injection, rock picking, green waste compost spreading and muck spreading.

Based in Pleasant Point, CIA Ltd contracts to farms throughout the Canterbury region, including North, Mid and South Canterbury. When he’s not out working on paddocks, Tom – often joined by Sandra – is on the road, relocating to new jobs.

We specialise in all forms of effluent application, both liquid and solid, using advanced European slurry equipment such as the Veen Huis Rotomax injection system for precise application.

What farmers say

Customer reviews

We have used Tom for both slurry and solid manure spreading since he started in business and thoroughly recommend his operation. They are very professional and with a great sense of (Irish) humour at the same time! The umbilical injection system is great as it saves on the huge amount of track/laneway wear and tear that heavy tankers create. He runs great, well maintained, clean gear and is a pleasure to have working on the farm.

We have hired Central Injection Agri Ltd for many seasons to empty our three dairy shed effluent ponds at Cumberland. We have found the direct injection system to be a quick and efficient method of emptying high effluent volumes onto paddocks. The umbilical piping system keeps our cow tracks intact and the direct injection allows the pasture to make best use of the effluent. We certainly see the results in the following season with extra grass growth. Tom and his team have always provided a professional service that is tailored to our needs. I have no hesitation in recommending their service.

We have been using CIA for 4 years now and won’t be stopping anytime soon! The results we are getting from the slurry injection are a real game changer! It is allowing us to skip 2 rounds of synthetic fertiliser across nearly 30ha which is a great saving! Thomas and his crew are great and make it look very easy! The best part about pond to paddock pumping is there is no issues with track damage, and it makes the process very fast!

We have had Thomas O’Keeffe pumping out our effluent ponds for quite a few years now and I have found him to be a genuine hard working guy, good to talk to and has always had competitive rates and works efficiently till the job is done. He will come ‘at the drop of a hat’ if you are having trouble being compliant because of pump breakdowns etc. which we really appreciate.
