Waimarama Surf Life Saving Club is putting a call out to the public to help them find the last lot of money needed to fund their "eyes and ears".
Plans have been in the pipeline for two years, but D-day is fast approaching with construction set to start on a new watch tower in just weeks.
In total $350,000 is needed for the project, of which nearly $200,000 has been raised so far.
The club's director of property James Laver said: "It is the eyes and ears of our club with views to the north and south of beach."
The cost of the tower had come as a surprise to the club but the location and need for it to suit modern technology was what had driven it up.
