Warren Marr, tournament coach for KIS, said it had been a great learning experience for the young Kamo cricketers had turned in an excellent Day One performance.
" Day 2 proved a little more difficult in windy and cold conditions and with the top order not firing there was pressure created on the middle and lower order. To the lads' immense credit they never gave up and pushed Hereworth within one run in a very exciting run chase.
"They can be very proud of the way they have competed aginst the best schools in the country, and it shows the depth that Northland cricket has within its schools and junior cricket as a whole."
