At week's end the top seven competitors in the four North Island events will go forward to the New Zealand finals.
"The sheep from Whangara Farms had pretty heavy coats on this morning because of the rain, but they still worked well," Mr Brown said.
"It was pretty difficult for us setting up this morning in that heavy rain but it eased up at just the right time.
"Everyone seems happy with how the champs have been set up and we have had lots of positive comment already."
It is an exciting day for young Whanganui-Manawatu dog triallist Phoebe Smailes as she makes her debut at the North Island and New Zealand championships, as a 14-year-old.
Phoebe, from Ohingaiti between Hunterville and Taihape, is the youngest competitor in the event.
"It's just another trial really, only it's the big one," she said.
She earned the right to compete in the championships with 12 qualifying points.
She won an open zig zag hunt championship in the Wairarapa with her four-year-old Sage and finished third in the Whanganui/Taumaranui/King Country "Young Guns" competition, against competitors much older than her.
"Sage is a clever dog. Dad started her off for me and I have finished her off," Phoebe said.
The pair will compete in the straight and zig zag hunts and they were to have their first run this afternoon.
"It does not feel that different to be here today at these championships.
"You don't get treated any differently just because you're the youngest competitor. Everyone is treated the same, which I like."
Phoebe went to her first sheep dog trial as a baby and it has been something she has always been keen on.
"I'm feeling pretty chilled about competing to be honest. I'm certainly looking forward to it."
Her father Jonathan said he was really proud of his girl.
"Phoebe's a quiet achiever. She puts her mind to it and just does it.
"She is a very determined girl."
Her dad will also compete with one dog in the straight and zig zag hunt events.
