Wellington city is edging closer to gaining a new sister.
Mayor Celia Wade-Brown has proposed Australia's capital city, Canberra, become our capital's next sister city.
Councillors will consider whether to formalise the relationship between the two capital cities a full council meeting on Wednesday.
Australian Capital Territory chief minister Andrew Barr is ready to sign the deal when he visits Wellington in early July.
Wade-Brown, who visited Canberra in April, said the new deal would bring the cities closer together, forging stronger economic, environmental, political, cultural and tourism ties.

"Together the capital cities will be stronger and have more impact on the global stage," she said.
"Wellington and Canberra have a lot in common and this relationship will help equip both cities for long-term success."
Businesses that provided services to the government sector had an obvious opportunity to expand, and the recent agreement with Singapore Airlines to fly from Singapore to Wellington with a stop-over in Canberra, was an example of what had already been achieved.
From September there will be four flights a week between Wellington and Canberra, connecting to Singapore.
The sister city relationship would also provide an opportunity to promote tourism from Asia.
