A fellow National Party MP - and doctor - helped discover colleague and former West Coast-Tasman MP Chris Auchinvole had heart problems.
Within days of mentioning to fellow National MP and doctor Paul Hutcheson that he was experiencing pain while walking up stairs, he had a stent put in an artery late last week.
Mr Auchinvole said today he was feeling better than he had in a long time, but had been told he could not work for three weeks.
"The cardio unit in Wellington kindly put a stent in an artery that they found was 90 per cent occluded."
He is not allowed to fly overseas for two months.
