New Zealand fast bowler Trent Boult and Bangladesh all-rounder Mahmudullah have been fined by the International Cricket Council (ICC) over separate incidents during the second ODI in Christchurch on Saturday. 

Boult lost 15 per cent of his match fee for twice using "audible obscene words" when the Black Caps were bowling. 

Mahmudullah, meanwhile, has been fined 10 per cent for striking a picket fence with his bat at Hagley Oval following his dismissal. 

In addition, the duo each receive one demerit point apiece - a first offence for both men. 

New Zealand won the game by eight wickets to wrap up the series ahead of the final instalment in Dunedin on Wednesday.
