Methven, the tapware manufacturer, reported a 39 per cent slump in profit after taking a $2 million charge on the collapse of its biggest British client.
The Auckland-based company made a net profit of $4.7 million, or 7.1 cents per share, in the 12 months ended March 31, down from $7.6 million, or 11.7 cents, a year earlier.
The company said this month that earnings would be hit by the voluntary administration of UK hardware chain Focus (DIY), which accounted for 5 per cent of total revenue last year.

"We've suffered setbacks this year, but we have learned from them, and in particular, are confident our strategies will return the UK to profit in the coming year," chief executive Rick Fala said in a statement.
