E whai pū ana te NSEN i ngā ratonga whakatika kore utu, whakakapinga kore utu me te whakahoki kore utu i roto i ngā marama 18 i muri i te whakakorenga o te takirere i ngā mahi tawhito, i ngā marama 12 rānei i muri i te tāutanga me te whakamahinga ki te paipa i muri i ngā mahi tawhito (ko tēhea te mea tuatahi). 

Mēnā ka pakaru te takirere nā te raruraru kounga i te wā e whakamahia ana i roto i te paipa i roto i te wā whakamana kounga, ka whakaratohia e NSEN he ratonga whakamana kounga kore utu. Kāore e mutu te ratonga kia ea rā anō te pakaru, kia taea ai te mahi i te takirere, kia hainatia rā anō e te kiritaki te reta whakaū.

I muri i te paunga o taua wā, ka oati a NSEN ki te whakarato i ngā ratonga hangarau kounga i te wā tika ki ngā kaiwhakamahi ina hiahiatia te whakatikatika me te tiaki i te hua.
