When this particular motif returns at bar 124 the oboes and flutes are
joined by the clarinet. Here is a good example of enclosure (between
the clarinet and oboe):

Throughout the work, the brass and percussion remain subordinate
to the woodwind and strings. Where they join the texture, it is usually
for the purpose of adding weight to climaxes, and reinforcing melodic
lines.
A number of differences between the orchestration in Aotearoa
Overture and Symphony No.2 movement I can be detected. However, in
pointing out these differences, it must be borne in mind that they are
not easily detected aurally, and that compared with the difference of
orchestration and textures between, for example, Symphony No.2 and
Symphony No.3, they are slight.
One of the most easily discussed differences between the
orchestration in Aotearoa Overture and Symphony No.2 movement I is the
range of the instruments, and the predominate tessitura used within each
instrument's range.
The string instruments, for example, all show a significant
extension of the upper limit of their range.

Aotearoa Overture and Symphony No.2 movement I.
