"The Far North District Council is behind it," said McLean, who has been involved in offshore boat racing forabout 40 years.
"I think it'd be really good for the North, because if anyone wants to see any offshore powerboat races they have to go to Auckland."
McLean, who is still racing at 73, said Northland only had a handful of racers and hoped this weekend's races might provoke some interest for new competitors.
The event will be filmed and shown on TV3's Gillette Motor Sport programme at a date to be confirmed.
Race day kicks off at 1.30pm with two races scheduled.

All about offshore powerboating:
Boats race in classes depending on types of boats.
Winners are decided based on times.
Boats start off racing as a giant pack.
Racing generally happens about 200-300m offshore.While announcers can usually be heard, it is recommended to memorise the names of local drivers or drivers of interest.
The term "Thunderboat" comes from the noise the boats make on the water.
