Flag change opposed by two-thirds - poll

Two-thirds of New Zealanders who took part in the latest ONE News Colmar Brunton poll don't want a new flag.

The poll, taken before the final four potential flag designs were announced, shows 66 per cent want to keep the current flag, up 2 per cent from 18 months ago.

There was a similar rise of 1 per cent to 28 per cent in those in favour of a flag change.

Fewer people are undecided, with the number saying they "don't know" down 3 per cent to 6 per cent.

But what makes a good flag?

Renowned vexillologist Ted Kaye says it should be distinctive, use meaningful symbolism, feature two to three colours and no writing.

"A flag should be so simple a child can draw it from memory," he said.

ONE News tested this principle with Year One to Year Six students attempting to draw the potential flag designs, with mixed results.

Some of the students found the koru shape, which features on one of the selected flag alternatives, challenging to draw, while others found it easy.

The fern, which is incorporated in the remaining three designs, was largely ruled too difficult to draw by the students.
