Young New Zealanders are more disgusted about the idea of using a public bathroom than the older generation.
A Canstar Blue survey has also found Kiwis are a clean bunch, with 65 percent busting out the cleaner on a weekly basis – though 50 percent say it's their least favourite room to clean.
General manager Jose George says young people would rather hold on than risk using public facilities.
"Those under the age of 30, we see about 67 percent who [avoid] public toilets, as opposed to men especially in the age of 40 to 49, who are more comfortable."
The number one bathroom irritability is a tie between finding hair in the plughole and urine on the toilet seat.
About 12 percent of Kiwis get irritated when people set up the toilet paper the 'wrong' way around.
