By comparison with other sites in New Zealand, the air in New Plymouth (taken as
representative of the air across the ring plain of Taranaki) was shown to be ‘excellent’
to ‘good’ according to the categories used by the Ministry for the Environment. A
review of monitoring around New Zealand undertaken by the Ministry has shown
that the Ministry’s PM10 guideline (twenty-four hour
