Mesui Tufui and Fisilau Tapaevalu have been on trial at the High Court at Auckland charged with murdering Abraham Tu'uheava and attempting to murder his wife Yolanda.
On Friday, the jury delivered a unanimous verdict finding both defendants guilty.
In April 2018, Abraham Tu'uheava was lured to Greenwood Rd in Māngere, south Auckland for a potential drug deal, the court heard during the trial.
There, he was shot at least seven times and died within minutes. It was a "miracle" his wife survived after she was shot multiple times in the head, the court was told.
