Davies' boys have played St John's College (Hamilton), Rotorua BHS and Fraser High (Hamilton) in pool B but not the top three of St Kentigern (Auckland), Westlake BHS (North Harbour) and Shirley BHS (Christchurch).
The introduction of a preliminary final - where the top qualifiers from each pool proceed to the quarter-finals - will allow the second and third-placed sides to battle it out in crossover matches to earn the right to face the automatic quarter-finalists.
"We haven't seen them [Cashmere] at all but they've beaten some of the top Auckland sides this year," he says as pool D will face crossovers from pool C in the repechage stage.
Expecting every game to be tough at the nationals, Davies says NBHS are backing themselves to make the top eight in the quest for the the Doug Harford Memorial Trophy.
The school won its maiden elite national crown in 1992 when Tall Blacks coach Paul Henare was a player.
Napier Girls' High School are seeded third, below Hamilton GHS and Auckland Girls' Grammar, in pool D of their "AA" grade.
The nationals will feature 69 teams, 800 players, and 268 games in their 50th year of existence.
