"At our school there are more parents taking students away during term time because flights are cheaper at those times, and flights are cheaper than they used to be," he said.
Nationally, the numbers of students taking at least one half-day holiday during the second term almost doubled from 23,192 in 2015, when the Education Ministry started recording the trend consistently, to 40,729 last year.
The average length of holidays during term time has been more stable, at 9.3 half-days in the second term of 2015 rising only to 9.6 half-days in the same term last year.
But the total amount of time students were absent on "unjustified" holidays increased from 0.4 per cent of the term in 2015 to 0.7 per cent last year.
Absences for an "explained but unjustified" reason have been steady at about 1 per cent of the term in each of the past seven years.
But unjustified absences with no explanation provided, or "truancy", have risen from 1.5 per cent of the term time in 2011 to 2 per cent last year.
"Justified" absences due to sickness also jumped last year, from around 4 per cent of the term in each of the previous six years to 4.6 per cent, due to a rise in "influenza-like illness" last winter.
Regular attendance rates are highest in primary schools and decline as students get older, but have declined over the past seven years at all levels - from 74 per cent to 67 per cent in contributing primary schools, from 74 per cent to 66 per cent in intermediates, and from 63 per cent to 55 per cent in secondary schools.
They have declined most steeply in the poorest communities - down from 57 per cent to 47 per cent in decile 1 schools, compared with a gentler decline from 78 per cent to 72 per cent in decile 10.
Asian students still have the highest regular attendance rate of 73 per cent, but even their attendance is down 7 per cent from 2011.
Attendance has dropped by 6 per cent to 67 per cent for European students, by 9 per cent to 52 per cent for Pasifika and by 6 per cent to 50 per cent for Māori.
Māori and Pasifika students were both absent without explanation (truant) for more than 4 per cent of the term, compared with just under 1 per cent of the term for Asians and Europeans.
However Māori, Pasifika and European students were all absent due to sickness for about 5 per cent of the term. Asian students were sick for only 3.5 per cent of the term.
