We operate the largest and most up-do-date specialist fleet and facilities in the country, designed to collect, transport, and dispose of hydro-carbon materials and waste to the highest possible safety standards.

Collection & Recovery


We provide an efficient North Island-wide service for the collection, recycling and disposal of waste oil.

We also provide a total disposal service for fuel oil slops, black and grey water from the shipping and automotive industry and major oil companies (view below).

Our service operates North Island Wide.


Our superior service and equipment makes the collection and disposal process fast and easy. We minimise interruption to your business and provide one-stop documentation.

As a registered collection agent for the R.O.S.E Recovery Programme.  This is a partnership with Fulton Hogan and Petroleum Services, offering Nationwide service between the two companies.  We cover more than 10,000 sites with our purpose-built collection fleet. Each truck is equipped with its own pump, hoses and calibration equipment, for pumping from large oil drums, storage tanks and machines. On return to our depot, we pump the waste oil into holding storage tanks for processing in the fuel recovery plant, and then it’s deliver to sites for industrial fuel. We also drain and crush the steel drums for use as scrap steel, and the plastic waste is shredded.



We also provide an oil filter collection and disposal service for workshops. We supply a large open top drum for you to fill with used oil filters, which we collect, compress and recycle.

For both waste oil and filter collection, we issue an itemised tax invoice, providing you with proof of legal disposal.

Spill Response

We provide comprehensive services to help our customers in responding to spills of hazardous materials of all kinds, including oil spillages.

photo-spilres-bigWe have the experience, skills and technology to deal with both major and minor environmental incidents.

The Auckland Council recognises our longstanding experience with rapid and efficient response to spillage incidents, and is one of our largest customers for these services.

Salters has had extensive experience in emergency situations. Examples of high publicity emergency response events attended by salters are:

We are also expert in proactively developing plans to deal with environmental incidents. As an example, we have developed a Tier 1 Spill Contingency Plan allowing us to react quickly and efficiently to avoid any product spilled reaching the ocean. This was developed through working closely with Ports of Auckland & Tauranga, Auckland & Bay of Plenty councils and Ports Harbour Masters as the approving environmental authorities.

Our Fuel Oil Recovery Plant

We own and operate a 50,000 litre distillation unit at our site in Wiri, Auckland. This gas-fired plant heats the oil to remove all water and contaminates, and has the capacity to handle up to 48,000 litres /day.

Waste fuel oil brought in from our collection operation initially goes into storage where any free water is drained off. The fuel is then pumped into the process tank and a sample is tested to check the contaminate level. It is then sent for processing into our gas fired plant which heats the oil slowly 135 degrees where light fractions and water evaporates and the contaminates are removed.  After the fuel oil is processed it is re-checked, then filtered to 400 microns and pumped into storage tanks to await shipping to customers to only approved and consented customers after testing.

This fully certified process has Worksafe and Environmental Certification.



Ship Slops, Grey water and Black water

We operate a specialist end-to-end disposal service for fuel oil slops, grey water and black water, mainly from the maritime industries.

photo-yard-bigWe provide a responsive, reliable non-stop service for all type of shipping and automotive operations, with no volume restrictions.

Our virtually unlimited disposal capacity means that we can offer long term contracts to both individual vessels and shipping fleets. We can guarantee availability of disposal and price for a consistently high standard of service.

We combine safe collection and processing, with the high temperature firing in OJI Fibre Solution’s kilns to guarantee that fuel oil slops disposal meets the stringent requirements of the New Zealand Maritime Transport Law.

We collect the waste fuel oil and transport to our own storage and recovery plant complex in Wiri, Auckland. This fully-accredited facility consists of 22 storage tanks, with a capacity of over 1.5 million litres. We process the oil at our recovery plant to remove water and other contaminants, and it is transported to OJI Fibre Solutions for fueling their Kinlieth and Kawerau kilns.

Our plant and facilities operate 24 hours a day, seven days a week, according to the strict conditions required by the Ministry of Environment and the EPA (Environmental Protection Authority), and waste water and air discharge regulations of Auckland Council.

Our Fleet

Salters Cartage Ltd owns and operates a modern and well-maintained fleet of tankers ranging from 4,000 to 45,000 litres.

photo-partners-holcimAll our fleet are fully-certified as Class 3A Dangerous Goods compliant. Each tanker carries its own pump, hoses and fittings, and we maintain our strict quality standards through regular servicing and testing of all this auxiliary equipment. Through our rigorous controls, we minimise the potential for incidents and environmental impact.

We demonstrate our commitment to minimising our fleet’s impact on the environment by ensuring our trucks are operated efficiently and minimise the social and environmental impact.

Each truck is fitted with a customised Eroad GPS, which means we can monitor in real time, schedule efficiently, and minimise unnecessary mileage. We plan our routes to reduce impact on the community. We can also set speed limit alerts in specific areas such as schools and inside business areas.

The trucks are fitted with drive-cam which monitors road incidents and driver fatigue.

All trucks have built-in speed control (90km/h max), reducing fuel use and emissions, and increasing safety. Our drivers have on-going training and annual auditing to reinforce defensive driving habits, reduce accidents, increase fuel efficiency and lessen the impact on the environment.
