NSEN ikutsatira mosamalitsa ntchito zokonza zaulere, kusintha kwaulere ndi kubwezeretsa kwaulere mkati mwa miyezi 18 valavu itatha ntchito zakale kapena miyezi 12 itatha kuyikidwa ndikugwiritsidwa ntchito pa payipi pambuyo pa ntchito zakale (ndipo imayamba poyamba). 

Ngati valavu yalephera chifukwa cha vuto la khalidwe panthawi yogwiritsa ntchito mapaipi mkati mwa nthawi ya chitsimikizo cha khalidwe, NSEN ipereka chitsimikizo cha khalidwe chaulere. Ntchitoyi siidzatha mpaka kulephera kukhazikika ndipo valavuyo ikugwira ntchito bwino komanso kasitomala atasaina kalata yotsimikizira.

Pambuyo pa nthawi yomwe yatchulidwa, NSEN imatsimikizira kuti idzapatsa ogwiritsa ntchito ntchito zaukadaulo zabwino pa nthawi yake nthawi iliyonse yomwe chinthucho chikufunika kukonzedwa ndi kusamalidwa.
