Rogers said these qualifications are some of his proudest achievements and he is looking for more study opportunities to expand his personal growth.
He wouldn't have got very far without such an "awesome employer", and the support of former senior caretaker Ron Sims, Rogers said.
"He has been an incredible mentor and I will always be very grateful for the absolute belief and support he has given me.
"My advice to anyone that wants to study is to use the direct support of those around you initially.
"Never give up, dig deep and believe in yourself."
Adam Saunders received a National Certificate in Infrastructure Works Supervision - Civil Works & Utilities (Level 4).
Originally a directional driller, he completed his first two industry training certificates with Infratrain in Palmerston North.
For the past four years, he has been a project supervisor for ultra-fast broadband with Downer in Hawke's Bay.
Unlike any other company he had worked at before, Downer asked him at the start of his employment what he wanted to study.
Saunders has also just completed a Business (Introduction to Team Leadership) Level 3 certificate as part of Downer's Inspiring Leaders programme.
As a practical, hands-on person, it had been great to have people to turn to for help when he needed it and he felt ready to go on to the next level, he said.
"If you're willing to do the hard work, you will reap the benefits at the end, and this is how I get things done."
Speaking to the graduates, Dalton said that support only took the graduates so far but this type of commitment took a great deal of effort from the individual.
"You are making a positive contribution to our community in so many ways, but I also ask you to never stop thinking about the future and asking, what's next?"
Hazlehurst said the graduates made a difference to the region's economy and the lives of the people around them.
"It is vital for our economy and the wellbeing of our community that we educate and train our people.
"It is vital we look after them, find them work and in turn continue to grow a skilled work force and a thriving economy.
"Now more than ever Hawke's Bay needs a skilled workforce. You are our future."
The ceremony was overseen by Eastern Institute of Technology head of Trades Todd Rogers with Peleti Oli from Somehz Touch Barbers as guest speaker.
Peleti, who incorporated a "hair art" demonstration into his talk, recently received the Pasifika Community Impact Award at the Got A Trade? Got It Made Industry Training Awards and was also the recipient of a National Certificate in Commercial Barbering last night.
