"We played really well but just let ourselves down with a slow run rate," he said.
"We can live with the result - I just think we let Taupo get away from us at the end of the first innings and so it was a tough target to try to get.
"I then thought we were too cautious at the crease. Our shot selection at times left a lot to be desired and I think we could have gone for it a bit more."
Geyser City shouldn't be too disheartened with the weekend's defeat however, as Lake Taupo finished the first round competition without the stain of defeat in their debut season in Western Bay of Plenty cricket.
The star of the Lake Taupo team was Roger Urbahn, who topped the bowling stakes with 19 wickets with a best of 7-16 and finished in the top 10 of the batting totals.
Geyser City secured just two wins in the first round - leaving them just above bottom placed Cadets on the table.
But Holmes said the team were aiming to make the semifinals in the newly formed Western Bay of Plenty reserve grade in 2017, with the competition splitting in two.
"We got off the bottom of the table and they were two very strong wins," he said.
"We can hold our heads up high. The team spirit has improved over the season and we can definitely make the semifinals next year.
"We don't have to make a lot of changes. It will just be about carrying on and having a better raw attitude. I think batsmen possibly need to place a higher price on their wicket and choose their shots carefully. It's onwards and upwards from here."
