Earlier, at least nine Indian nationals or people of Indian origin were feared missing in New Zealand following the deadly terror attacks at Al Noor and Linwood mosques in Christchurch, unofficial sources said on Friday.
The death toll in Friday's terror attacks at two mosques in Christchurch rose to 50 with victims ranging in age from two years to over 60 years, New Zealand Police Commissioner Mike Bush said on Sunday. Earlier, police had said that 49 people were killed in the twin attacks.
He informed that 50 people were wounded in the mass shootings.
Giving out details of those injured, Bush said that 36 of them are undergoing treatment at Christchurch Hospital and three persons, including a child, remain critical at Auckland's Starship Hospital, New Zealand Herald reported.
The country's police chief also confirmed that Brenton Harrison Tarrant, the 28-year-old Australian-born suspect was the sole attacker who carried out the Friday's attacks at the two mosques in the city.
Tarrant, who appeared before a Christchurch court on murder charges on Saturday, was remanded in custody without plea until April 5.
The terror attack suspect, who live-streamed for about 17 minutes his rampage through two mosques in the city, is an Australian-born citizen and is a resident of Dunedin, situated around 360 km south of Christchurch.
Condemning the terror strike, New Zealand Prime Minister Jacinda Ardern had described the attack as "one of New Zealand's darkest days" and said it "appears to have been well planned". She asserted that the country "will not and cannot be shaken" by the attack.
Ardern underlined that the country's gun laws will undergo changes and become stricter.
