Miller and George were unlucky in the final, but for the first time this season they were able to finish a Gisborne meeting with their bike still running.
Miller has had to change the motor in his bike seven times this season.
They finished fourth in the final after three firsts and two thirds in the qualifying heats.
“Red and I were stoked to get three wins,” Miller said.
“That was our first full meeting since October. It felt brilliant.
“We finished without blowing a motor and we are definitely not race-fit.”
The title was won by Peter Adams and Jason Hira (6A), ahead of Kenny Hammill and Daniel Bradley (11A). Then came Ireland and Symon, and Miller and George.
In the support programme, the Cook brothers Ethan (1NZG) and Daniel (77G) shared the wins in the four-race saloon car series.
The current national champion won the first two heats and his elder brother, the second two, with Daniel Wallace (15G) also prominent among the finishing stats.
Shaun King raced particularly well in the streetstocks, with two firsts and two seconds.
The stockcar class turned on a great night’s entertainment in their “best pairs”, which was won by Bryce Harding (79G) and Trevor McArthur (128G).
Mason O’Dwyer (99G) and Clinton Cheetham (36K) finished second and Jason Lovell (167G) and Jamie Harding (71G) were third.
“It was an awesome meeting; every race was just right on,” club president Neil Gooch said.
“The track surface was brilliant. It was so fast, and some great lap times were posted.”
He paid tribute to Clyde McGrory and his team for the track preparation.
This weekend the track hosts the teams demolition derby, saloon champion of champions, and youth ministock best pairs.

“I was pretty rapt to pick up second place,” Wright said.
“It was a bit of a bonus, given my lack of luck at the New Zealand event in Gisborne.”
Crystal Peach (3NZ) went from pole position in the final as top qualifier, but a flat tyre cost her in the final. Dave Gooch (1NZ) finished fifth.
