By March 1953 the Ministry of Works became concerned at the progress being made by the consortium and that their management team lacked the experience to construct a hydro power station, which was highlighted by the large amount of rework being undertaken. Progress was not helped by the Government directing the employment of a large number of assisted immigrants many of whom had little construction experience and limited English. In early 1953 at the government's expense the consortium flew out 309 workers from Great Britain.
