The Ministry of Health advised anyone who was at the Rotorua Lakefront on January 13 between 6.15pm and 9.30pm and January 15 between 10am and 2pm should self-monitor for Covid-19 symptoms for 10 days after they were exposed.
If symptoms develop, get a test and stay at home until you get a negative test result.
Also anyone who was at Lake Tarawera on January 13 between 3pm and 6pm and January 15 between 2.30pm and 5pm should also self monitor.
A Ministry of Health spokesperson said Lake Tarawera was added as a location of interest "out of an abundance of caution".
This was due to the large number of people who were at the lake at the time, the amount of time the case spent there, and the general movement of people at the lake.
"Anyone who was at Lake Tarawera at the specified time is asked to self-monitor for symptoms for ten days from January 13."
This advice does not include people who were on boats that did not have contact with any people they did not know.
