Statistics NZ says nearly 42 per cent of the under-20 population are non-European or a mix of European and other ethnicities.
Children are also being exposed to different cultures in their homes as their family members travel, fall in love and bring up children here.
No young person says ethnic diversity is a solely bad thing.
Taralee Harvey-Brown, 10, of Rotorua says: "There's been quite a few Japanese and stuff coming over, it's okay if we don't go over the top, because we are only a small country."
What of those born overseas but who call this country home?
Charlotte Binks, 18, who was born in England but moved to Christchurch when she was 10, identifies herself as proudly British but keeps surprising herself by claiming New Zealand success on the international stage as her own. "I guess the idea [of being a Kiwi] has kind of grown on me."
The last word on diversity goes to Tatiana Tango, 10, who talks about a past South African teacher who she thought was cool even though his pupils were naughty. "It makes no difference to me because I take the personality of the person in front of me."
The question
Who are we?
What does it mean to be a New Zealander in today's interconnected world?
The context
The "typical" New Zealander who will read the new compact Herald is much harder to pin down now that we are more likely than ever either to have come here from overseas or to have been born here and gone.
The methods
A DigiPoll survey of 750 New Zealanders plus in-depth interviews with 91 people in New Zealand and 16 NZ-born people in Australia, including similar numbers in five 20-year age bands. The NZ interviews were arranged with the help of primary schools spanning the decile range in north and west Auckland, Cambridge, Rotorua and Christchurch. In addition historians at the online encyclopedia Te Ara selected 30 key events that helped shape our identity over the past 100 years.
The team
Greg Ansley, Kurt Bayer, Simon Collins, Yvonne Tahana, Lincoln Tan, Vaimoana Tapaleao.
