Fisher & Paykel Healthcare is forecasting a 38% rise in first-half profit, to the end of September.
The company told shareholders at its annual meeting in Auckland on Friday that trading for the 2009 financial year had been positive.
It said demand for its respiratory and acute care products had been particularly strong.
Turners Auctions' half year result is up by more than half, driven partly by a strong lift in sales of repossessed vehicles and car-related finance and insurance.
The company says its net profit increased 55% to $812,000 for the six months to June, compared to the same period last year.
Chief executive Graham Roberts says the result's good, given the second-hand car market as a whole was down 6.5%.
