But as she paddled next to her young team, an orca popped up just metres from the bow of the waka.
The sudden appearance of the giant mammal caused some concern among the paddlers, aged 8 and 9. The stroke decided it was a very close encounter and he ducked down inside the waka, while the others let out yelps.
"Once I calmed them down and reassured them, they were all so excited. They realised how special it was and what an experience to have."
It was not long before a crowd gathered on the waterfront at Onerahi to watch the orca. Two small light aircraft and a helicopter also took in the spectacle from above.
Miss Ferguson said it appeared the orca were feeding out in the channel, as they were swirling around as if they were rounding up their prey.
The kids asked for a team name change after the experience, wanting to be called Miti Orcas, not their original name Miti Minions.
Onerahi resident and keen photographer Wendy Giffin said the orca display was spectacular, with them swimming so close to shore.
"I saw the fin, then the spray into the air. Then they were right among the boats."
There were reports of orca being spotted near McLeods Bay earlier in the day.
