What you need to know after National’s leak saga.

A businessman who rogue MP Jami-Lee Ross alleged provided $100,000 in donations to Simon Bridges hosted the National Party leader for dinner, his wife says.

Auckland resident Yikun Zhang became a member of the New Zealand Order of Merit in September for his services to New Zealand-China relations and the Chinese community.

SUPPLIED Yikun Zhang with Governor-General of New Zealand Patsy Reddy after receiving an Order of Merit for services to New Zealand-China relations and the Chinese community.

In an explosive interview from Parliament House Ross said he had a recording which proved Zhang had donated $100,000 to Simon Bridges, which were then handled in a corrupt way.

Ross alleges the payment was split into smaller donations, and not disclosed to the Electoral Commission. Candidate donations of more than $1500 must be declared in a candidate's return of expenses and donations.

ROSA WOODS/STUFF Outgoing National MP Jami-Lee Ross makes new allegations against leader Simon Bridges at Parliament.

He is founder and chairman of Chao Shan General Association - an organisation of New Zealand Chinese who share the same hometown of Chaoshan, a region in the coastal city Guangdong, China.

In July National Party deputy leader Paula Bennett posted photos on her Facebook page of her and Jami-Lee Ross sitting at the same table as Zhang for the opening of the Chao Shan General Association's new function centre.

The Chao Shan General Association also has members in mainland China, Hong Kong, Macau, Taiwan, Vietnam, Laos and Cambodia.

Chao Shan General Association of New Zealand was founded on the basis of Chinese (Chaoshan) culture. It aims to unite all Chaoshan people, making contributions to communication and cooperation between New Zealand and China, and enhancing the development of both places.

It recently donated an ambulance to St John.

COLLETTE DEVLIN/STUFF National leader Simon Bridges responds to rogue MP Jami-Lee Ross' accusations of corruption.

In 2017 Zhang was part of an Auckland Council business delegation to Guangzhou.

The delegation was to provide Auckland businesses with a chance to explore business and investment opportunities with contacts from Guangzhou and Los Angeles.

An Official Information Act response relating to the Southland District mayor Gary Tong's relationship with Zhang said the mayor and his partner received a sponsored return trip to China to attend business and local government introductions in Beijing and Guangzhou.

"In return he has presented Mr Zhang with two legs of fresh lamb from his 10-acre block and four live crayfish from a fishing trip," the response said.

He also hosted Zhang in Southland.

Zhang is honorary chairman of Chao Zhou Association, through which he has organised a range of events and initiatives for the Chinese community.

He established a youth branch of Chao Shan and a scholarship scheme for young achievers.

He organised a number of New Zealand companies to attend the Canton 21 Century Maritime Silk Road International Expo in China and organised an economic and trade cooperation conference between New Zealand and Hainan China.

He also played a key role in securing hosting rights for Auckland to hold the 20th Teochew International Convention.

The Teochew International Convention has been held biennially since 1981, and allows more than 3000 participants from around the world to gather and solidify their economic and cultural ties with the host city.

A receptionist at KCC said Zhang could not be emailed as he did not speak English.
