Destiny Church co-leader Hannah Tamaki has once again splashed out on a new Mercedes-Benz - this time it's a 577-horsepower twin-turbo V8 beast.

Public records show Ms Tamaki took ownership of the black 2017 Mercedes-Benz AMG GLE63 S SUV on August 15.

The vehicle sells for $207,900 plus on road costs from Auckland's Armstrong Prestige.

The SUV is an upgrade on Ms Tamaki's previous vehicle, an AMG GLE 450 coupe with a 3-litre twin-turbo V6 engine purchased about a year ago.

Following that purchase - the second high-end Mercedes-Benz purchase by Ms Tamaki within seven months - some criticised her, saying it was greedy and unbecoming of a church leader running charity to drive such a lavish car at the expense of church members.

Destiny Church spokesperson Anne Williamson told 1 NEWS the Tamakis were "surprised at the media's intense interest in their private lives".

"What car they drive is not news," Ms Williamson said.

"It is also a concern to know how you acquired this knowledge, and we will be looking in to that."

The records were acquired by 1 NEWS through a publicly-accessible government website, and Ms Tamaki has also tweeted a photo of her new car.

She then tweeted about the criticism, saying "What u spend ur $ on, ur business" and that she wishes she could have an even more expensive car.

Destiny Church was co-founded with Ms Tamaki's husband Brian Tamaki - a self-appointed bishop - and their charitable organisations are tax-exempt.

Members of the church are reportedly required to pay 10 per cent of their income to the church as a tithe, as well as being encouraged to give more in special giving drives.

In July, 1 NEWS revealed that Charities Services was looking at their approach towards "serial late filing" from charitable entities such as Destiny Church.
