Oliver Yates has told the ABC he plans to officially petition the High Court in coming days, sitting as the Court of Disputed Returns, to examine the outcome in the Melbourne seat of Kooyong.

The challenge will be based on what he describes as misleading campaign advertising from the Liberal Party, which he argues tried to mimic the colouring of official Australian Electoral Commission posters.

The signage, in Chinese, told voters to place a "1" next to Mr Frydenberg's name.

Labor had foreshadowed it would challenge the result in the neighbouring seat of Chisholm, based on Chinese-language campaign material posted on social media platform WeChat.

Now the Liberal Member for Chisholm, Gladys Liu, has denied authorising the how-to-vote card, which warned voters their ballot could be invalid if they did not follow the preferences as set out on the flyer.

However, the material was posted to Ms Liu's personal WeChat account.

Labor has yet to follow through on its threat.

Challengers have 40 days from the return of the official election writs to ask the High Court to consider the result in any electorate.

The writs were returned on June 28.
