Owen Ona

Founder

For Owen, real estate has never been about chasing titles or selling more homes. It is about trust, responsibility and the people behind every decision. His journey from growing up in the Philippines to building a life and business in New Zealand shaped the way he sees success: something earned through hard work, humility and how you treat people. That perspective has become the foundation of his career. Whether arranging a private viewing late at night, guiding a first-home buyer or negotiating a campaign, Owen brings the same honesty and commitment to every client. He believes service should never depend on someone's background, budget or circumstance.

That mindset has driven remarkable results. A Rising Star Award winner in his first year in Christchurch City, Owen has gone on to deliver more than $200 million in sales across Canterbury and build a reputation as one of the region's standout negotiators. Known for creating momentum where others see difficulty, he has revived tired campaigns, uncovered hidden value and turned challenging properties into exceptional outcomes. Behind every result is sharp strategy, relentless work ethic and a belief that success means more when it is built without compromising the values that got you there.

Reviews

Owen has become a part of our family and Owen is different from other agents. He puts in all of his time and goes above and beyond to make a sale. He also ensured us that we are happy with the buyers he introduced and negotiated till he got the right price for us. Owen's honesty, commitment and loyalty to both the buyer and seller are rare qualities we have come to appreciate.

The moment you contact Owen, day time or night time, he will respond and look after you. I asked him if we can view the property at around 9pm and he made it happen on a very short period of time. At 10pm a decision was made, we will join the auction the next day and we won. Thank you so much Owen for your assistance on our purchase. Great service indeed. 10/10
