The pair are both due to appear in the Auckland District Court tomorrow.
A scene examination is continuing today in Saintly Lane and is expected to continue for some days yet.
Police are also asking for sightings of a black-coloured Honda Stream vehicle, registration HLL620.
"We believe this vehicle travelled from 19 Saintly Lane to nearby Rosebank Drive and we'd like to speak to anyone who may have seen it at about 4.30am," said Schmid.
The Herald understands the homicide investigation is centred on the Mongols gang.
The Mongols were first established in the United States in 1969 and spread to 12 countries, including Australia, where they quickly earned a reputation for ruthless violence.
The Mongols arrived in town in 2019, the first New Zealand chapter of the Australian gang was established in New Zealand last year after influential members were deported.

Earlier this year, escalating tensions between the Mongols and Head Hunters gangs led to police arresting 19 people in relation to a spate of serious arsons and drive-by shootings including gunfire at an Auckland inner-city hotel.
In mid-2020 police arrested 10 people who were either members or associates of the Mongols, who they described then as an "organised crime group" in relation to drug dealing, firearms and money laundering.
