Acute stroke unit clinical nurse manager Amanda van Elswijk said every year about 9000 New Zealanders have a stroke, with some dying and others facing a long recovery.
"Recognising the signs can spare thousands of New Zealanders the pain and heartache of having themselves or a loved one seriously disabled for the rest of their lives," van Elswijk said.
"One of the biggest challenges to improving a person's chances of survival and recovery after a stroke is having them diagnosed as quickly as possible."
Clot-dissolving drugs (thrombolysis) and clot retrieval technology (thrombectomy) can halt and reverse the damage caused by stroke but they must be administered as soon as possible.
University of Otago research has predicted a sharp rise in stroke cases over the next 10 years unless better prevention measures are put in place.
"We really don't want those forecasts to become a reality – we want people to lower their stroke risk by living healthy, active lives and make sure those predictions don't come true," Vivian said.
"It's not too late."
