Medium is defined as "a terrorist attack is assessed as feasible and could well occur", but it means police need not routinely carry firearms.
"We're adjusting our times to suit specific requirements of the local Muslim community and we'll obviously respond to any urgent calls for service," Huys said.
"At this stage, we haven't been made aware of any suspicious behaviour in and around the local mosque but we'll continue to work closely with the local Muslim community to
determine what their current needs are and constantly adjust our plans based on the feedback received."
Huys said one of the positives in Northland as was seen throughout the country after the Christchurch shootings was the considerable public support towards the Muslim community.
Muslims fast from sunrise to sunset during Ramadan and refrain from all food, drink, tobacco use and sexual contact. Those excused from fasting include the elderly, children, the ill, travellers, pregnant women, nursing mothers and those menstruating.
Muslims are also expected to avoid gossiping, lying, envy, greed and other bad character traits during the month-long fast.
Muslims in New Zealand fast for about 12 hours during shorter winter days compared to more than 19 hours in Europe or about 15 hours in the Middle East.
There are about 60 mosques and Islamic Centres in New Zealand that cater for about 50,000 Muslims.
Ramadan is the Arabic word for the ninth month in the Islamic calendar, sometimes rendered as Ramazan in other languages.
As the Islamic calendar is lunar (organised by the cycles of the moon) and the Gregorian calendar used by most Western countries is solar, Ramadan's timing in the Gregorian year shifts by roughly 11 days each year.
This year, Ramadan falls across the Gregorian months from early May to early June. Last year, it fell 11 days later – from mid-May to mid-June.
