Our Story

Steph Jansen from New Zealand hails from the Bay of Plenty.

I grew up in the small mill town of Kawerau before moving to Auckland to join the Police. I left the Police to move to Tauranga to be closer to my family and began working as an administrator.

In NZ, I was ready for the challenge of being self-employed. Every so often I would see an ad for the Reef Sub pop up and I didn’t initially consider it due to the off-shore location. After Christmas last year I went back to work and had a feeling that I couldn’t face working long hours having my son cared for by other people for another year, so I took ‘the leap of faith’ and bought the Reef Sub. I did my research and had a good idea as to what I was getting myself into.

Steph, who is qualified to pilot the vessel, said the Reef Sub typically caters for families and couples of all ages.

So what should visitors know about Reef Sub when thinking about taking the cruise? That it is not a lagoon tour, it is an outer reef tour, so you have the opportunity to see pelagic fish, turtles, rays, sharks and whales (in season).

Our aim is to share with our guests a beautiful side of ‘off-shore’ Rarotonga that will captivate and entertain them, and that will be a lovely memory of their visit to the Cook Islands.
