Commissioner Mike Bush said they will be at commemorative events to mark the one-year anniversary of the terror attacks.
"There will be an increased police presence in Christchurch over the next few days, with officers at a call to prayer at Horncastle Arena (on Friday) and the National Remembrance Service on Sunday," he said.
Police will also be present at local mosques and a number of other events throughout NZ.
"In some locations officers will be armed."
Commissioner Bush said he will attend the service on Sunday at Horncastle Arena to honour those injured and killed.
"The events of March 15 changed our country forever," he says.
"These unprecedented attacks mark the day we lost our innocence, but out of something so awful we saw so many acts of bravery, empathy and kindness.
"The anniversary on Sunday is an important milestone for us all, and for police, an opportunity to reaffirm our commitment to keep New Zealanders safe and feeling safe.
"I’d like to acknowledge the dedication and professionalism of all police staff working that awful day, and every day since to achieve that goal.
