Omokoroa fire fighters are battling a scrub fire on Jess Rd measuring about 100m by 120m.
Fire service shift manager Colin Underdown said it appeared to have started as a controlled burn which had got out of control.
One fire crew was at the Whakamarama address using a high pressure hose on the light scrub.
An Omokoroa fire fighter said the fire was down by the estuary.
