Police officers found weapons and improvised explosive devices in the cars of the people arrested.
Before the shooting, the man uploaded a 73-page manifesto explaining in detail why he'd committed the massacre, according to local media reports.
A spokesman said the attack happened as some of players got off a team bus and were about to enter the mosque.
President Trump offered his condolences in a social media post, saying, "My warmest sympathy and best wishes goes out to the people of New Zealand after the frightful massacre in the Mosques".
"We are dealing with a very serious and tragic series of events in the Christchurch-Canterbury area", police chief Mike Bush said.
He was later asked if he had seen the New Zealand shooter's alleged manifesto.
He tweeted: "Our hearts go out to the people of New Zealand following the news of this awful act in Christchurch".
"Many of those who will have been directly affected by the shooting may be migrants to New Zealand". They are us. The person who perpetrated this violence against us is not.
