The Ministry also says it has never promised to establish a dialysis unit in the kingdom.
Speaking to Kaniva News, Dr Sione Latu said the claims of 60 deaths were an exaggeration.
He said the last clinical audit in 2016 showed 38 cases who would be on dialysis if they were overseas, of whom five subsequently died. This was in line with world statistics.
Dr Latu was responding to claims reported in the New Zealand media from a Tongan man who was admitted to Middlemore Hospital two days after he arrived in the country with end-stage kidney failure.
