Some scientists had thought that humans came to NZ 1,000 years earlier than 1,300 AD ???
Then those scientists are dumb...
First the Moa Hunters came...
Then shortly after or about the same time the Maoris sailed in from Tahiti in their 7 out-rigger canoes...
That was about 900-1,000 AD...
About the same time another group went to Hawaii)
And about the same time the Vikings arrived in America...
Any NZ school kid could have told the scientists that...
"Martin Doutre's book, "Ancient Celtic New Zealand", suggests strongly that the ancient peoples who inhabited these shores before the Maori arrived, had the knowledge and culture of folk with a kindred "Celtic" civilisation. This extended to stonework and standing stones, the working of stone, artstyles (from which current Maori styles appear to have developed along with other contributions), petroglyphs and possibly even into language."
