Etuini Ma'u of Waikato Hospital said there had been an increase of anxiety and depression among the elderly.
Pacific families needed to take extra care to ensure their elderly were supported during these uncertain times, Dr Ma'u said.
"The impact of lockdown is affecting the elderly deeply. There's been an increase of anxiety and depression. The longer this drags out, the harder it will be for them," he said.
"It's about maintaining that social connection and recognising that this is a very disruptive and uncertain time for your parents, for your elderly."
