Four people with gang links have been arrested on Waiheke Island on Friday.
The group had warrants for their arrest and were breaching their bail at the time, police said.
One of the men was wanted for a violent kidnapping in Beach Haven on April 2.
Detective Sergeant Ray Fa'aofo, from Waitematā's Offender Prevention Team - Investigations, said the search warrant began at 4.30am with police descending on an Oneroa address on the island.
Detective Sergeant Fa'aof said the address was housing people connected to the Mongols gang.
"Police quickly took four people into custody without incident at the address.
"Amongst those we located was the 25-year-old, who was wanted for arrest over the earlier kidnapping."
This man has been the subject of ongoing police appeals alongside countless enquiries by the investigation team.
Detective Sergeant Fa'aofo said he will appear in court to face serious charges including:
- Kidnapping
- Commission of a crime with a firearm
- Committing burglary with a firearm
- Wounds with intent to cause grievous bodily harm.
The man will also face a charge of possession of a firearm and ammunition after he was found with a loaded shotgun.
He is expected to appear in the North Shore District Court later on Friday by way of AVL.
The early morning search warrant had assistance from other specialist police groups including Operation Cobalt staff, Armed Offenders Squad, Eagle, Auckland Police Maritime Unit and staff from Waiheke Island.
"At the address we arrested three other people that are connected to the Mongols gang," Detective Sergeant Fa'aofo said.
Two men, aged 30, will be appearing later today in both the North Shore and Auckland District Courts as they were wanted on breach of bail charges.
A 46-year-old woman has also been charged with being an accessory after the fact over the kidnapping, and breach of bail.
She will also be facing ammunition charges and will appear in the North Shore District Court later today by way of AVL.
"This group may have had weekend plans, but this morning's warrant has changed that and instead their trip is to face their matters in court.
"Our team has been working for countless hours in recent weeks to locate the man sought over the kidnapping incident.
"It is pleasing we have now located all of those that we allege were involved in that violent incident."
Detective Sergeant Fa'aofo added that the investigation team acknowledged the ongoing support from the public during this operation.
"Our focus remains on targeting those people who think it's okay to engage in this gang violence and inflict it against the community.
"We will continue to take enforcement action and hold them accountable."
