"There was a hint of maturity in the fact that we didn't panic and the goals came. It is about getting the higher percentages in the areas we want."
Taupō also progressed to the second round after a 3-0 shutout of Auckland side Uni-Mount Bohemian Celtic. Jordan Lamb scored all three of Taupō's goals.
The draw for the second round of the Chatham Cup is due to be released on Tuesday, and the competition changes pace as the premier teams from around the country, who had a bye in the first round, enter the fray.
Tauranga's focus now shifts back to the Northern League Football first division, which will play round nine fixtures this Saturday and Tauranga, who sit in sixth place, host third-placed Bucklands Beach at Links Avenue Reserve.
"It is back to training for us," Millichip says.
"The Chatham Cup is a bonus, it is a wonderful competition, buy the league is our focus."
Tauranga have three wins, a draw and three losses this season and Millichip wants to see the team continue to improve.
"We are pleased with the style of football and what we are putting out there and it suits the players we have. We would expect to be pretty competitive [against Bucklands] and we focus on getting points at home."
McDonalds Ngongotahā Men's NRFL first team, who did not play in the Chatham Cup, also resume their season in the second division as they host second-placed Claudelands.
Ngongotahā have had a tough start to the season, without a win from seven games.
