Meet the Bio Oils Team

Our Management team consists of Daryl and Debbie Prebble, husband and wife team, Nick Swift and Jenna White (their children) and our Office Manager, Amanda Evans, who keeps us all in shape!  We are supported by a superb Production and Warehouse team who assist with the smooth day-to-day operation of the business.

Daryl Prebble

Head of Production & Quality Control

I was born and raised on the Prebble family farm, and from a very early age was out with my father Gavin, driving the tractor. It was therefore natural for me to attend Lincoln University, achieve a Diploma in Agriculture in 1985, and take over management of the family farm.

In 1996 I formed Independent Seeds, a speciality grain and seed trading company and brokerage. I took over the ownership of Bio Oils in 2006, giving me the ideal opportunity to utilise my knowledge of the New Zealand grain and seed industry. Debbie joined Bio Oils in 2009, and together we have grown Bio Oils into a specialised cold-pressing business, with a focus on New Zealand grown, fully traceable, cold-pressed flax seed oil and flax seed meal. 

Debbie and I married in 2014, and together we enjoy spending time at home and travelling overseas to visit my son Miles in Hong Kong, and Debbie’s family in England. When not in the Bio Oils production room or visiting my farmers, I can be found at Lake Benmore fishing! My favourite fishing spots are Ohau C (Lake Benmore) and Lake Brunner, and my favourite catches are Rainbow and Brown Trout.

Interesting Fact: I won a baby competition when I was 18 months old… I had a lot more hair then too!​


Debbie Prebble

Head of Business Development & Operations

I first arrived in NZ in January 2007, on holiday from England with my daughter Jenna. Two weeks before we were due to leave NZ, I was offered a two-year job contract, and so we decided to stay in this amazing country.

In 2008, I met Daryl, and the rest is history! I joined Daryl at Bio Oils in September 2009, to assist with sales and marketing activities. I had enjoyed several sales roles in England, including new business, account development and team management, and these skills have enabled me to develop and grow amazing relationships with our Bio Oils customers. My goal is to grow our markets, both domestic and overseas, and to deliver the finest quality, fully traceable NZ products to our customers.

I have two children, Nick and Jenna, who both work alongside Daryl and I at Bio Oils, making Bio Oils a third-generation family business!

Apart from working on our businesses, I love to read, cook and more recently have started to knit! I also love to visit the lakes, and relax by Lake Benmore.

Interesting Fact: I like to ride sports motorbikes, and until very recently had a Honda CBR600RR, which I loved.  I’m a grandma now, so thought the bike should go!

Jenna White

Head of Domestic Sales and Marketing

Over 10 years ago I came to New Zealand on a travelling holiday with my Mum (Debbie)…thank goodness she was offered a job contract so we could stay here and call this beautiful place our home!

I enjoyed 3 years of study at the University of Canterbury in the stunning garden city of Christchurch. Following the devastating earthquakes there, I then moved home to Ashburton and was offered a wonderful opportunity to join our family business. I thoroughly enjoy the rewards and challenges working in a family business brings – sometimes at weekends we do have to consciously stop talking ‘work’, but it is great to combine our individual skills, knowledge and passion towards achieving the very best for our businesses. 

In 2016 I married my husband Alastair, an Agri-Business Banker, and we bought our first home together that same year. Outside of work I enjoy travelling both domestically and overseas, cooking, reading and shopping!! When time allows, I also enjoy spending time at our holiday home in Lake Tekapo with my family and friends.

Interesting Fact: I’m 6ft 2’ but I was always terrible at netball and basketball! Shopping for trousers can be a challenge!

Nick Dytham-Swift

Head of Compliance & Export

My wife Leoni and I first came to New Zealand on holiday in 2007, and we knew straight away this was a great place to live.  So, in 2010 we made the permanent move to settle here in Ashburton. 

I joined the Bio Oils team in 2011 to assist with the growth of our retail brands, and export operations of the business.  I now oversee all aspects of export for Bio Oils and our brands, and I am also responsible for the smooth operation of our factory as well as Health & Safety and Food Safety compliance.  I thoroughly enjoy working with all our overseas clients to meet their requirements and grow the export side of our businesses. 

Away from work I enjoy playing a variety of sports and am a keen skier in the winter time.  Leoni and I also enjoy travelling around New Zealand visiting new places.  The outdoor lifestyle is something that first attracted us to living in New Zealand, and we like to try and make the most of that as much as we can.

Interesting Fact: I became a father in March 2017, to a son named George who enjoys keeping us on our toes!

Amanda Evans

Head of Administration and Accounts

I have been a member of the Bio Oils team for six years.  During this time my role in the office has grown steadily in line with the growth of the businesses.  What started as a part-time role, which fitted around my school-aged children, has grown into the full-time position I now have.  Being a part of the huge growth of Bio Oils and its brands has been such a buzz, although the increased workload can cause a few headaches from time to time!

I come from an administrative and customer service/hospitality background which stems from a love of being organised and more importantly talking. 

I met my husband, Drew, whilst working as the assistant manager of the Fox Glacier Hotel on the beautiful and rugged West Coast of New Zealand. Since then, we have raised to teenage years, two children, Caitlin and Ethan. Hopefully, we can survive these next few years and release them as adults into the big wide world.

When I am not at work I can usually be found traipsing around the countryside with my children attending their various sporting events.  Both of them are currently cycling in the summer and in winter time it's gumboots to the fore for hours of standing on the sidelines at rugby and soccer.

Interesting Fact: I suffer from Globophobia which is an irrational fear of balloons popping.  (Yes, it is actually a thing!)
