A while ago, Australian and New Zealand wiring codes were amalgamated to the standard AS/NZ 3000. So the rules are the same.
Recently we bought some equipment from Europe, and it would also have had black wiring for three phase. We got them to put heat shrink Red, White and Blue over the ends of the phases. A second solution was that any cables that they ran in the field, that is not pre-wired, were to be purchased locally. That way we knew that it conformed to local standards.
I have copied some of the standard below:
AS/NZS 3000:2000
3.8 IDENTIFICATION
3.8.1 General
In general, insulated conductors shall be identified by the colours given in
Table 3.5 to indicate their intended function (such as active, neutral and
earth/equipotential bonding conductor).
Where a combination such as green/yellow is used, one colour shall cover
not less than 30% and not more than 70% of the surface, with the other
colour covering the remainder of the surface.
TABLE 3.5
COLOURS OF CABLE CORES
Identifying colours
Earth/bonding, Recommended-Green/yellow Alternative-Green (see Note)
Neutral Recommended-Black Alternative-Light blue
Active Recommended-Red Alternative-Any colour except green/yellow, green,yellow, black, light blue
NOTES:
1 Where a required earthing conductor is not normally manufactured, a suitable
insulated conductor may be used but shall be identified along its entire length by a
green coloured sleeving.
2 In New Zealand, the use of the colour yellow to identify active conductors may
continue but will not be permitted in the next edition of this Standard.
3.8.2 Core identification
Coloured identification at each termination may be used for live conductors,
using one of the following types of material:
(a) Heat shrink sleeving.
(b) Fixed sleeving.
(c) Elastic sleeving requiring a special applicator.
Core identification shall be colourfast, permanent, non-conducting,
compatible with the cable insulation, and suitable for the location.
Green/yellow, green or yellow colour insulated conductors shall not be
sleeved to indicate live conductors.
Generally, we use colours Red, White and Blue for three phases. These were specified in the old (1992) eddition of the code.
Hope this clears it up.
