Transport Supervisor Andrew Petersen’s day begins at 6am at Winstone’s Awatoto Sand Plant on the coast in sunny Napier. Andrew is responsible for transport logistics for the whole of the Hawkes Bay. He ensures the smooth running of a fleet of 5 Winstone Aggregates and sister company Golden Bay Cement trucks, as well as managing an on-call supply of 15 owner drivers in the region.
Andrew began working with Winstone Aggregates in 2007 as a driver and his career progressed into a supervisory role last year. With a background in quarrying, transport logistics and driving, Andrew was well placed to take on a supervisory role, and is a highly respected member of the transport division. In 2013, Andrew’s region won Most Improved Transport Site at the Winstone Aggregates’ company awards.
“I’ve always had an interest in trucks, and Winstone has a great fleet as well as an excellent health and safety record. With 5 plus trucks on the road at any one time, and a huge variety of projects across the Hawkes Bay, this job certainly keeps me on my toes,” he says.
Andrea Cave is Winstone Aggregates’ Environment Manager. She’s responsible for the management of the organisation’s environmental, including improved biodiversity, and sustainability functions. With a Master’s degree in Geography (majoring in Resource Management), Andrea’s background includes roles at various Auckland councils as well as international experience, in particular the United Kingdom where she held a number of environmental management positions.
At Winstone Aggregates, Andrea is responsible for ensuring compliance with conditions of consent, management plans and district plan rules. She develops and oversees many of the organisation’s environmental management plans and administers Winstone Aggregates’ Environmental Management System, an ISO 14001 framework used to manage the environmental effects of the business.
Following a review last year, Andrea rewrote the system to better ensure accountability for environmental performance with a structure that encourages openness and environmental improvement at all operational sites.
While the impact on the environment can be significant, it need not be negative, Andrea says. “Our strategy is to achieve net environmental benefit”.
The costs involved with transporting aggregates mean that many quarries are located close to, or within urban areas. Managing the equilibrium between the economics of quarrying and its effects on the environment, and the local community, is challenging. “Often, people aren’t aware of the important contribution that aggregates make to our everyday lives and so don’t appreciate the need for our operations.” Andrea works with local communities to establish a social licence to operate at each Winstone Aggregates site; her aim is to leave neighbours with a good impression of Winstone Aggregates. “There is always a high level of interest in our quarry operations so we hold regular open days so locals can see how Winstone Aggregates operates and the ways in which
manage our effects.”
Winstone Aggregates also makes a significant investment in sponsorship. Andrea’s objective is to change relationships from charitable recipients to alliances to that create diverse benefits for both partners and added value for communities. “Our sponsorship programme allows us to demonstrate our commitment to local communities, and the environment.” Trees for Survival, a hands-on environmental education experience where children grow and plant native trees and shrubs, is one such case. Winstone Aggregates supports three schools financially, and with company time. During a school planting day at Cue Haven, a rehabilitation project north of Auckland, Andrea saw a further opportunity to contribute; Winstone Aggregates is now providing the project with aggregates to create new paths and tracks.
After working on both sides of the compliance fence, Andrea is proud to work for a company with a good reputation and an excellent compliance track record. She enjoys the diversity both inside and outside the quarry gate, the people, the environment… “Quarrying is an exciting and diverse industry” says Andrea. “Every day brings new challenges. It keeps you on your feet!”
Business Unit Manager
Originally a Venezuela-based oil exploration geologist, Tim has extensive international experience in aggregates, ready mix concrete and cement, having spent eight years with RMC (now CEMEX). While at RMC, he managed Taffs Well, a 60 hectare limestone quarry. High on his list of achievements at the site was the construction of a £4,000,000, two-lane tunnel to improve road access. At 200 metres in length the tunnel was also wide enough to accommodate two-way quarry traffic.
Prior to his role at Winstone Aggregates as Business Unit Manager, Tim managed Hunua Quarry. “Managing the organisation’s largest site during a recession wasn’t easy. Our first sub-million metre year since 2002 was difficult to manage: for quarry development, at Hunua there are some challenging pit areas with geotechnical face stability challenges.” But at the same time, massive successes contrasted the difficulties. Employee engagement improved and in terms of health and safety, significant improvements were made to the site’s safety statistics. “There is a strong team spirit at Hunua Quarry. The guys do genuinely look out for each other. It’s a real credit to them — the site’s over 2 years LTI free.”
During his time at Hunua, the site also won multiple awards for environmental and community initiatives, undertook country’s largest quarry blast and supplied cement treated basecourse (the most significant amount of its kind in New Zealand history) into the 20/1 project, as well as hundreds of thousands of metres of other products.
Tim’s enjoyed tracking the benefits that efficiency projects have brought to the site. Already underway when he arrived at Hunua Quarry, the HP4 (tertiary cone crusher) installation brought improved throughput and better tailored product yield and three new CAT 775F dumpers improved production. “The guys love them. They’re safe and efficient and use less fuel — they’re definitely a huge improvement.”
He’s also enjoyed the strategic element. “I’m a strong believer that if you get it right at the quarrying excavation end, if you get the volume and the quality right at the start, everything else flows on from there. If the plant breaks down you can repair it; if its catastrophic you can get mobile equipment in. But, if the rock’s not there, then nothing happens. I recommend a three or four month blast plan — when a quarry gets towards the end of its life you need to be pretty methodical, keeping a long term view in mind.”
