Hayes have provided a reliable spraying service to us for many years. Their experience combined with the right equipment mean they can get the job done at a reasonable price and timeframe. We highly recommend Hayes Spraying.


I just wanted to share a quick note and let you know that you guys do a really good job. I’m glad I decided to work with you. It’s fantastic how good your communication is and flexibility with spray availability. If there is problem, you sort it quickly. Our turf is weed free and looking good as you not only provide weed control but apply fertiliser and wetting agents as directed. It used to take me three weeks to control weeds but now you do it in two days.


Hayes Spraying Services have undertaken chemical vegetation control throughout the rural roading network of the Whanganui District for the past 15 years. During that time they have proven themselves to be reliable and consistent in their approach to delivering a quality outcome oriented service. Their long serving employees have come to know and understand the ins and outs of our district’s requirements which assists them to deliver an efficient service. This is also aided by the companies continued investment in modern high quality equipment. At times of high demand, when additional work is required or queries are made as to programme completion, Trevor and Jon have always provided prompt and efficient information and service to accommodate our requirements. I have no hesitation in recommending Hayes Spraying Services should you require chemical application.


Over the last three years Higgins Family Holdings Ltd have made considerable use of Hayes Spraying to spray for both general weed growth and also for areas where gorse has become a problem. At all times the work has been carried out in a timely manner and the success rate has been 100%. In residential areas where a degree of care has had to be taken so as to only spray what had to be sprayed, and where members of the public were present, all appropriate precautions have in my experience been taken by Hayes Spraying which speaks well of their Health & Safety Protocols.
